Hopefully you do an updated report on the much awaited for XT Outback. Ordered one October last year and test drove one yesterday and found the power delivery horrible with huge turbo lag, very slow off from the lights and found lots of flat spots. They have also meddled with the suspension to allow for the additional towing capacity which I found degraded the ride. I consequently cancelled my order and settled for a new Forester which felt more responsive around town and saved 14k in the process and will save more money on fuel and insurance. What where Subaru thinking by detuning the power plant compared to the US models, very disappointing. Also test drove the new xtrail epower, now that thing is impressive and smart drive train technology.
Very racist opinion you got here... Really disgusting this kind of reporting about surfers stories and other 'oral' stories you received often. spread hate, that is all you can do.
Two main corrections: Cars are NOT hot dip galvanised, which would make them distort and be too heavy, and rough surface finish. They use pre galv sheet, usually with annealing process to form zinc iron alloy (galvanneal) which spot welds much better than gal due to the iron content. This is textured and gives best coating adhesion. ALSO at least important is the development of e-coat (wet electrostatic paint plus baking) which creeps into crevices and coats everything. I was an engineer in the car industry for 20 years, plus 10 years in outdoor non rusting products.
Thanks for putting this up, as it seems to be what I thought. the dip in car production decades ago (when I was at Jaguar) was "phosphate dip", and was most certianly not molten zinc, and was for paint adhesion as much as anything else, not corrosion resistance.
Worked at ford 50 yrs back as apprentice in body shop and paint. Correct about paint adhesion
I've seen rust you people wouldn't believe. Alfa Romeos falling apart on the shoulder of Orion road. I watched C-pillars disintegrate in the darkness at mum’s house. All those moments will be lost in time, like tears in rain. Time to fish oil…
Well played Rutger
Alfa romeo, Lancia and fiat are well known rot boxes.
Even today they don't do well.
Underrated

My pride and joy as an 18 year old was a 76 Valiant Regal.. as bits fell off it due to rust,I referred to the process as organic lightening.
BYD is just exploring reducing its footprint.
Lol you 18,, a 76 valiant and me as 18 in my 76 xc falcon ,, and yeah had sort of same problem ,, but it was still solid , very solid as it ended up into the red gum trees at 65 kmh and the bumper turn inside out , yet all doors opened properly still , front of car was totally panel destroyed ,, yet under Neath 100% still dead straight and drove spot on still , I had seat belt on when I hit tree and it didn't feel that hard impact cause every thing went splat ,, credit Ford,, that car didn't even ruffle my hair when it crashed, after 9 years with me
Yes I was thinking P76 as well. Someone should give BYD a history lesson so they know how rust can kill a car company.
John you are correct in part with regard to automotive sheet steel being galvanized, although the process starts with the sheet steel rolls supplied to the car manufacturers. The steel sheet undergoes a continuous hot dip galvanizing process in a Zinc-Magnesium-Aluminium alloy bath, producing what is termed (ZM) HDG-Coated Steel Sheet. This is all done prior to forming the vehicle panels and frames, the process of forming and assembly doesn't affect the coating as adhesion is excellent and it is sufficiently ductile to avoid cracking, also the welding processes are not affected by the coating. The picture of the vehicle going into a bath that you displayed was actually part of the painting process, which ensures thorough cleaning and application of primers. There is a good video on you tube of the 'BMW Paint Shop' paint process although no narrative of the process is provided. The alloy used for galvanising the steel provides a much finer grain size over normal Zinc galvanizing, which is necessary for a high end paint finish.
The rustproofing and paint quality of German cars is outstanding.
Detroit started galvanizing rocker panels in the sixties. Yes the fenders would rust away, but in most cases the rocker panels were pristine. In the US it was the early Japanese imports that did not have galvanized rocker panels and turned into total rust buckets.
Detroit did not initially galvanize the whole body in part because it tended to affect the paint finish, a big deal on fenders but not so much on rocker panels. Another issue was that rust through usually took 3 to 5 years, so that the original owner who bought the car new usually never saw the rust. As cars became more expensive, car loan terms increased from 2 or 3 years to 5 years. Now the banks and finance companies who held the car loans became involved and pressured Detroit to make more durable cars to protect their collateral.
Great video. I am a kiwi. I recently helped my grandson do a body transplant on a 2010 Nissian Narvada 4x4. It was a work truck which had a hard life. Very impressed, no rust at all in the places we don't normally see. I have a 2017 Iveco Daly van motorhome, Yes I live by the beach, there is enough under body corrosion to make me think. The van came from Austrialia , and I can't really find any information on what manufacturing treatment was done on the underbody. I have decided to do a annual application of Fluid Film a lanolin base grease/oil anti rust mixture you spray all over the under body and inside internal cavities. I feel if you live in a salt rich enivorment , or drive on the beach your car corrosion protection may fail.
In NZ they do not put neat pure salt on the roads like they routinely do in the UK at the first sign of snow. This is why so many of the older cars in NZ are still in excellent condition as regards to rust. Living close to the sea does present corrosion problems though, even in NZ. They sell Fish Oil to spray the steel panels with but the smell is a bit off-putting and you end up having to explain to passengers why there is a smell of fish in your car! I guess the Aussies have no problem with that though. The aerosol can that I have here is called: "Australian Export Fish Oil, made by Oweno (Sales) Pty. Ltd." There's only two things that smell like fish, and one of them is fish as they say in NZ.
EV direct from March 2022 said the " The galvanising process of the chassis used by BYD is Electrophoretic Coating "
Are you sure that wasn’t catastrophic coating???
Thanks John. Good insight into this potential problem. Lets see what BYD does so far as issuing further information.
Cars when made in Australia were not hot galvanised dipped. BHP however provided a product name zincaneal which had some protection. However if you were an owner of EA to BA Ford Falcon, it was not enough to stop rust in certain weld joints when the PPG etxh primer failed to reach during the body shell dipping process before robot painting of colour.
Common places for rust were between: radiator support and skirt panels; strut top panels; bonnet strut mounting balls on the body; boot/tailgate strut mounting balls; door hinges and pillars.
Cars made in australia were.
Renault used a process called electrophoresis on cars made here from the late 60s onwards.
Except for a 6months or so period in about '72 (when someone sabotaged the dials on the machinery. Took them that long to realise there was a problem. Those cars rusted as you watched.)
Spent time in China, would actively avoid BYD taxis because they were always totally clapped out in comparison to a VW or Toyota of the same vintage.
Absolute crap ...
Parents purchased a Mitsubishi Montero new in 1987. I am pretty sure it was not galvanized given how fast it reverted to ferrous oxide
First car was an EJ Holden with a custom fitted plank of wood in the driver's footwell to cover a rusty hole you could stick your leg through. Carpet was luxuriously arranged over the top of it. Drove that car for 3 or 4 years before the powerhouse grey motor gave up the ghost.
Mine was an FJ Tony and I didn't bother to cover the hole - was amusing to see the road rushing by underneath the car. Seriously.
Going way back, when I was a child living near Detroit, our family Fords, you could hear them rust away. The 58 fords had rust holes by 1963 that you could throw a softball through. It didn't help that they had no splash shields in the wheel wells. Same thing later on with my 1968 Mustang, within 5 years there were several golfball-sized holes in the fenders. Our neighbor was a mechanical engineer and he had his grad student come out and acetylene weld patch panels in their Chevy fenders. It was just taken as a given that cars would rust out in 4 years.
Yeah, had a Fiat in the 70s. Structure finished after four years from new. just a crunchy mess.
Still no rust on my 1968 Mustang, except for a bit of surface corrosion on the inside of a fender where something stored in the trunk must have leaked prior to my 1978 purchase. So it depends on where you live. I remember well how cars in the USA Northeast looked while I was going to college there: Lots of unrepaired dents on fairly new cars, since they were just going to rust out sooner than later anyway... Edit: ... and in general a whole lot of things on cars back then which didn't work very well or for very many years. It wasn't until say the mid-1980's or later (everyone old enough will have their own version of where to place the date based on their experiences) that USA cars started to reflect the sort of reliability and build quality which is now taken for granted.
BTW ~1978 my mechanical engineering class took a field trip to the Ford manufacturing plant in Framingham MA. About the only thing I remember from it was looking through glass into a room where unibodies (for the new Fairmont?) disappeared beneath the surface of a zinc bath or whatever they were using. Some sort of full-frame coating by then.
Paint seemed to be largely for cosmetic purposes back then and serious new owners would treat their vehicles with after market products to prevent corrosion. One was a thick bitumen based paint which pretty much sealed everything from the atmosphere and was popular on underbody areas, but created a worse situation if moisture and existing corrosion was already underneath. Fish oil, which was pretty much unprocessed was also popular. My first car was a 1967 Holden HR panel van here in Australia. It had been treated with fish oil (basically poured inside doors and allowed to drain out drain holes and any other body cavities or channels where rust would eat away at the pretty much untreated steel.) Car smelt like fish but was still fairly rust free in 1975. By then manufacturers were starting to get better painting and anti corrosion treatment processes. At least we don't have the issue of salt here in Aus which a lot of northern hemisphere countries apparently have with de icing roads during winter.
@@davow8 Yes my father had some green gunky stuff applied inside the doors and fenders. It helped with those areas but then the rust just worked extra hard, double speed in other areas impossible to spray.
Great video! Also worth noting: (especially in the UK) NEVER EVER use a roadside hand car wash, these people mostly use sodium hydroxide and/or Hydroflouric acid in their wash process which is absolutely terminal for aluminium, steel and glass. They often recycle the water, so the runse water is also contaminated,
@Retired Bore Well it's not concentrated acid, but you are 100% right about the dangers and it is used. I've personally looked at the containers their car washing fluids are carried in and the ingredients are clearly labelled and that's where I saw sodium hydroxide (caustic soda) is also used. Believe it or not I've seen these car washes operating in multi-story car parks, goodness knows what the damage to the structure will be. www.icwgroup.com/workers-compensation/library/icw-group-risk-management-hydrofluoric-acid-brochure.pdf
@Retired Bore No, there are rules, just not enforced, I can ensure you that in 2023 it goes on... www.parliament.uk/globalassets/documents/commons-committees/environmental-audit/hand-car-wash-evidence.pdf
Sounds very unlikely. Glass and steel are not harmed by those harsh chemicals. HF acid is toxic and expensive. And aluminum body panels are rather rare.
@@georgegonzalez2476 You need to re-read your school chemistry: "and aluminum body panels are rather rare." This is not true. Jaguar, Tesla, Land-Rover, Mercedes-Benz, BMW and many others make use of aluminium panels not to mention that virtually all cars have aluminium wheels. Glass is corroded by HF acid (goes misty) and the reaction between caustic soda (sodium hydroxide) and aluminium is exothermic. Steel is also corroded by HF acid. The document I liked to above explains this. en.wikipedia.org/wiki/Hydrofluoric_acid
I'm more bothered that they all employ illegal labour to staff these outfits and they are very often fronts for laundering drug money.
Dad's CM Chrysler rusted around the rear window and bottom of doors like a ghost disappears after his soul is saved . I remember attending a House , as a Phone tech ,near the Osborne Sub building base . She was a Metallurgist being brought over to assist with the corrosion problem. I always battle Internet and Phone line problems to corrosion and telecom network along the LeFevre Peninsula. An area sandwiched between Ocean and Salt tidal River. Galvanising still corroded over decades
Little bit of confusion about galvanizing John. Hot dip galv. is as you say, the body, trailer whatever, dipped in molten zinc and provides a coating that is measured in 10th's of a millimeter. Electro galv which, is as per the photo with a car body going into a bath, is measured in micro-metres, about 1000 times thinner. They don't hot dip car bodies because, using your figures of weight per square metre, would double the weight of the vehicle.
how can 70g/m^2 of hot dipped zinc double the weight of a vehicle? If a vehicle is 1 ton, you would need another 1 ton of zinc, which would be 1,000,000 grams. This divided by 70g equals 14,285 square metres of surface area. Divide by 2 for both sides, equals 7142 square meters. I dont know about how you calculated your numbers, but there is no car on this god's green earth with a surface area of 7,142 square meters or even an order of magnitude near it.
Agree - there's likely no hot dipped components aside from possibly some hardware / fasteners. I'd speculate that the electroplating is applied to the coil steel prior to stamping and spot welding of the body, and the dip line coating is less likely a true zinc electroplating and more probably an e-coat paint process which may have some dilute concentration of zinc in the primer solution
If you HDG the average car body you'd not have one straight or flat panel on it when it came out of the bath.
Always wondered, what is the value [if any] of Cad plating? does that "goldy" stuff do anything?
Ecoat not galvanizing is the main encapsulation process that prevents rust on todays cars. However there are many other strategies in play to really put an end to rust.
I deal with hot dipped galvanized cable tray on a daily basis and I can tell you it DOES rust in certain conditions, the number one condition is usually dissimilar metal corrosion caused by using fasteners or brackets made of a more noble metal such as stainless or aluminum. Generally these reactions only take place when some kind of electrolyte is present (Such as water)
Galvanized steel isn't the mystical indestructible thing you make it out to be.
Galv bolt & Stainless bolts + salt-water in a wooden pier caught fire. I went out to put it out and the stainless bolt was glowing RED-WHITE holt like it was in a forge. The two bolts started rubbing together and caught fire.
As an engineer and past member of the Australasian Corrosion Association, this is true, but you have to do something "very silly" for galvanising to break down rapidly in a motor vehicle application. Galvanising works extremely well in motor vehicle bodies. (I have 75 year old galvanised pipe fence posts which will outlast me.)
@@martintaper7997 Correct me if I am wrong; the colour of "rust" is a visual indicator of the localised redox conditions for iron?
@@TheLargino Yes, "rust" is a form corrosion, and this car shows a lack of corrosion protection, maybe none at all, just the finishing paint coverage, which is entirely inadequate.
Yes - what you have described here is classic "galvanic corrosion". Two dissimilar metals and an electrolyte (dirty water). There will be hydrogen produced and 10s of milivolts across the contact.
I do love the look of the BYD vehicles but I haven’t seen them underneath. However I have seen the undersides of a number of LDV vans. Two of them lying down on the side of the road. The amount of orange and brown penetrating rust on the floor pans and chassis rails surprised me. These are new vans that you can poke a screwdriver through. Reminded me of the obviously raw cheap steel that had a light dusting of paint used in the cheap pit bikes and quad bikes. They just dissolved.
Funny you mention LDV vans, my work mate is on his third. The rear floor and axle keep separating from the rest of the body due to rust. The first one just had the floor fold and drop out the bottom when loaded.
Ldv have been in Europe since 2010. They have their problems there but rust isn't one of them.
When has China produced anything reliable or of quality?? (Not being a douche) But come on, whether it be electronics, white goods or vehicles… your being a hopeful Guinea pig!!
…your just adding to landfill!
@@madmick3794 right. So they keep buying them. I believe you.
@@lukeclifton4392 um. Iphones?
Had an old Alfasud 1979, in those days the MOT wasn't as strict...... There was more filler in the wings than metal and the windscreen surrounds had so many holes it was like aircon.
As The Sweet once noted…
‘Rust does like oxygen,
You get too much kiss the BYD goodbye,
Not enough and your atmo car dies,
Rust ate my 81 Gemini.’
Ahhh, the Sweet. Little Willy set me free to go on a teenage rampage in the wig wam bam next to Blockbuster...
Comment, sung to the tune of Love is like oxygen.Sweet!
Only the finest chinesium for Australians! I’m not sure why MG cars need an annual rust inspection.
I was looking at BYD Atto3 but decided to wait a bit & see if problems popped up. Phew,
Galvanizing is just an electro plate. Scrape it, over heat it (spot welding during assembly), exposure to acids and salts, abrasion and it will (and commonly does) fail.
THANK you! Luckily NIL such thing for my Atto3. I live in the West Coast of the most humid country in the world Singapore🙏🏼🌞😄🌴 exposed to the maximum: land and sea saltish breezes everyday, next to the saltish sea!!!!! I'm a doctor, my brother runs a car mechanic shop! We were so scared seeing the two pictures surfaced recently, that I ordered him to take apart my EIGHT MONTHS old Atto3 exposed to rain, heat, salt and more!!and he did, he took things apart in those parts you mentioned and more! RESULT: NIL CORROSION nor RUST 🙏🏼😄🌴🌞🌞🎋
That is exactly the kind of test I want to see.
@@jman8128 well, yes!😄😁🙏🏼 These photos are easily done. Likely wrecked vehicles. As mechanics in a wreck yard, we can easily induce these rust too. Anyway with American corporations, things go VERY deep. These can be paid for by a rival EV car company or retailer, out of malice. With several T*** vehicles losing electronic control in the past few months and crashing, killing the occupants inside. Somebody needs to strike back at BYD to bring down their sales. E.Vik. also claimed that his wife had Stage 4 cancer, claiming that he needs the money otherwise he has "to sell his house". And guess what? After procuring more than thousands successfully, he went to buy a Cybertruck. Wow.

Prove it ! There's HUNDREDS of comments on Reddit of Aussie owners talking about these problems.
In the seventies I owned a 1970 Peugeot 504. It had a galvanised body and obviously not Japanese. It was also far ahead of it's time mechanically.
It must've been a great way to avoid having to fork out for child support.
Gotta endorse that, Trevor. The Peugeot 504 S/W I ran around in during the early 1990s was built like a tank. Last year sometime a 504 was being advertised for sale at a good price. I was keen, nostalgia is a wonderful thing, called the seller but the 504 had gone. The seller reckoned that he could have sold the car ten times over from the enquiries he had received.
I had a 71 504 with the 1.8L and it was a tank of a thing, the independent suspension and 4-wheel discs made it a great handling car. They were a bit heavy I think at about 1400-1500kg and the 2L: later on when the 1.8 died eventually was quite a good engine in terms of torque, less revvy but made it an easy cruiser. If I ever come across a 505 sedan I'd probably snap one up as they were quite a good vehicle as well.
The last great Peugeot.The 505 was more modern and pretty good but did not last as long.It was all downhill from there, the 209 gti at least drove well.
My 2003 Citroen C5 was galvanized and had a 12 year rust warranty.
Thanks John for corrosion in steel tutorial. I was taught the thin gold coloured treatment on components was cadmium.
Have seen new, unregistered,DFSK trucks( Chinese) at UK dealers, already having rust on edges of steel panels,on tailbords/sides.
Previously worked for a LDV dealer. Inconsistent build & component quality, cheap for a reason
I can't believe that this car is a bigger rust bucket than the XD Falcon panel van that I (briefly) owned during the 80's.
Found On Roadside Dead!
You're basing your comment on what information? Did you actually watch and understand the video from John Cadogan? It doesn't sound like it to me.
I worked in a panel shop and we found the exact same rust under any panel that was removed on a new Chinese made MG. No way would I spend my hard earned on a Chinese built vehicle.
Chinese build to a price point...as with most chinese products they are designed to last a short time....
I remember hearing years ago that the best manufacturers ionize the steel in there autos and this greatly reduces the rust problem.
BYD has a option box called rust . This box is pre checked.
I’ve just called Byd customer service asked them about the rust and the lady said they use every step to prevent rust. I’ve also asked if they use galvanised metal on the chassis and the frames she said yes they do. I’ve got one in order arriving in few days and I am excited but kinda worried too 🤷🏻♂️
Look under the car once a year and apply galvanising spray to rust spots. It's more than adequate
😂
*Looks to me like "Galvanic corrosion" due to dissimilar metal of the fasteners on the BYD car, you cannot use a fastener of a very different iron content of the base metal, it happens with stainless steel bolted to anodized aluminum.*
I’ve had 2 Mahindra Pikup , Indian made export , which have had rust in a couple of places , mainly behind the front wheels
People do not know but in Europe, we do not buy Chinese steel as the Sulfur concentration is making it prone to rust and fail...
When I was in High School my dad got me a summer job at the Ford Assembly plant. union, great money for the time!
Summer they had a 2 week shut down to switch over to the new model year. New machines were installed as required. Old parts were cleaned out. Part of the cleanup was to "bury mistakes". As the "new guy" we had to work through the break. I got to scrap several racks of brand new unpainted doors, because they were rusty (hadn't been stored properly at that factory, "lost" in a corner somewhere, what ever. Safer, easier, cheaper to scrap them than to try and clean them and sell them. I also got to dump several 5 ton truck stake beds that had been cut in half. Someone was half asleep and welded clamps in the wrong place. Not easy to cut them off to put them in the right place. Model year end, chop them up, put them in the dumpster recycle the metal and no one has to explain what happened, why. No blame.
Check out russian sites. One of their many build quality complaints about Chinese EV's is rust and light weight metal. Another is about bad joints letting cold air during the winter. The cars just don't do well on russia's roads outside of Moscow ...
Friend's car was a Datsun 120y. We called it the Flintstone's mobile because each year the rusted hole at the bottom got bigger and bigger. Yes you could see the road below the car. No idea how it managed to pass rego each year.
Because it was South Australia and annual roadworthy checks didn't exist then????
I miss my 120y. Regret it massively, getting rid of it 30 years ago.
'79 Holden Gemini - same. Ahh, the memories... and terror.

Having been a citizen of the U.S. rust belt at the time, an auto body technician and also living 30 miles from the lake Erie humongous salt mines, where you dig huge cave through the salt deposits under the lake, so the stuff cost a few dollars a ton, I can state without a doubt after repairing rust on severall two and three year old Honda Civics and Accords from the 70's including my fathers, the Japanese proficiency and prolific use of spot welds negated any positive effect of galvanizing, which I never saw on any part of a car where it would have stopped anything, and was patchy at best.
Conversely, I've repaired rust on several 1960's Ramblers that actually rusted out ABOVE the galvanized rocker panels.
Both the Japanese and Americans started expanding their use of galvanized panels around the same time.
Including providing escape points in the body to prevent air pockets in susceptable areas, like fender tops, agitation mechanisms or spinning the body over.
The vehicles longevity of both countries benefitted greatly from the practice.
But the Japanese auto makers certainly weren't any better at it, and didn't start the process first, though they did very well with the process.
I think it was CHINA OBSERVER that highlighted the soft subframe metal.
Bent easily with a shifter.
WOW John what a comprehensive discussion on the galvanic process... No 30-yo could have made this video! Many thanks
Hi John,
Speaking of rust, have you driven over the Sydney Harbour Bridge recently? While not strictly about vehicles, would like your opinion on the numerous and large amounts of what appears to be rust on the beams.
Relax it'll be a soft landing
I noticed the rust also.It is because Hoges is no longer painting it.
Don't stress too much. The entire bridge is painted yearly....it takes an entire year to paint it!
What would John know? He is not a building engineer. Relax the bridge is fine.
@Scott William I think he has said he is a mechanical engineer. Being a STEM grad meant a bit more back in the day than now too.
This gave me a replay of my VL Commodore rear window nightmares back in the late '80's.
I wonder if the Chinese lack of galvanization, at least in the more built up coastal areas, is designed to limit the age of the vehicles before they require replacement. The increase in rusting will likely limit ages to 5-10 years without additional protection by the buyer. Remember the old Fish Oil treatment we used to do here in Australia in the 80's and 90's? Yeah I can still smell that
dont be ridiculous...they galvanize them there too, its not such a big deal. All the people in CN live on the coast of Pacific so they have a lot more rusting there.
The Chinese are about the only ones to hotdip galv their export trailers, they must have a reason, I know most people will buy a galv China trailer than an Aussie made non galv.

I think in China, all cars are written off at the age of 10 years, it's compulsory.
Couldn't be surprised about them rusting already!
The whole Chinese industry, automotive and civil industries are corner cutting enterprises period. I wouldn't expect any of them to last the distance. Time will tell
That's why Aussies built their own space stations. Their imaginary minds have consistently take them to a place far far away where no other human beings have visited. This is often with the help of their national swimming coach.
1 quart any oil new or used, 1 quart of trans fluid new or used, 1 tube of grease, 1 wax toilet gasket. Heat and mix all. Use any way u want. Pap worked for Ford in Ohio by Lake Erie. Friend drove a post war ford sedan. In late 60s he asked How do u keep that car so nice when all others rust away. He showed him what it looked like and told him write this combo down. Pap told me as a teen in 1990. He used this till he died in 2019. All things u don't want rusted. Guaranteed to work better, longer and be cheaper, $5-10. Knock off heavy rust, use Ospho or muratic acid for bad places for 10 min, wash with water and baking soda, use Eastwood chassis saver, farm implement paint or rustoleum. Then cover with this. No rust for 50 years. U can add whatever u like to it. Boiled linseed oil, etc. If I need to thin I use hydraulic fluid. Stuff it tough. Your welcome. Pass it on to all ppl who love things with motors or things made of metal.
At the turn of the century, the company I was working for (Coleman Milne), who made limos and hearses had a problem with the MB E class, which was becoming too electronically complex to be jury rigged after conversion to make it run. COMPUTER SAYS NO syndrome. So they asked Ford, who also dumped them in the cart by stopping Scorpio production mid sentence, if they had any other suitable cars, and they came up with an Australian market Ford 4 door sedan (Fairmont? Fairlane? Can't remember) and it seemed to work, except, being cheapskates Coleman Milne had them shipped seafreight from Australia as deck cargo. Cue lots of seagull sh*t followed rapidly by lots of underside corrosion, as the Australia market cars were not undersealed, and rot holes in wings in under 12 months were not abnormal.
Appreciated your discussion about steel and galvanization. Learn some new things. Well done!
I still have my (over 700,000km and now with historic plates!)1979 ZJ 5.8L Fairlane with very minimal rust kept under control all these years by the annual liberal use of 3-4 cans of FishOil. Yes cars of the 70’s just loved to fade into rust heaps from the moment they left the showroom . More than happy with my 2016VF SS with 250,000Km coming up :) no squeaks no rust .
Sorry what oil? FISH???

15-20 yrs ago when Tata took over Rover MG in UK, I worked for a dealer, and when we started getting 'new' spare panels for for Tata rebranded as Rover vehicles parts were already extensively rusting.
Here in Sweden at least and probably all over Europe it wasn't the Japanese who first galvanised their cars, it was Audi with ten years rust warranty. Sometime in the mid or late 1980s.
Japanese cars on the other hand were considered no good against rust.
Not a problem in New Zealand: the law covers you and BYD is on the hook for 15+ years from new for replacement or full repair depending on when the problem is caught.
And if the NZ distributor drops the brand or goes belly up, no chance of getting 15 plus years warranty. The NZ law means nothing in China.
@@grahamdontcare8620 Christ, does it hurt being you or are you just naturally that thick? If the NZ distributor drops the brand they are still on the hook for products they have previously sold. Any distributor that takes on the brand assumes that liability. The dealer going bust is a problem, but BYD leaving NZ is not a make/break event: NZ law can and has been applied in Chinese courts before, so you could, in theory, follow BYD back to China. As an individual that's unlikely, but as a group action, entirely within the realm of possibility.
@@iatsdditto for Aus Consumer Law. The retailer/distributor is the first entity on the hook.
Most Excellent video - being a semi non Car expert this video is an eye opener; thanks for an excellent informative video
I am intrigued by the fact that some new car buyers are prepared to purchase Chinese made vehicles, yet expect their new pride and joy serve them well 🤔🤔
Riddle me this....... since when has " Made in China" equated to quality?
They build to a price point....and a short life...
Sacrificial Anode. Doesn't come up in conversation often. I first learned the term in the late 70s, helping my dad replace the chunk of Zinc on the leg of the outboard, on his boat.
Great band name.
They have just strapped several ton of zinc to an old submarine sunk off the coast of Australia to preserve it. Why beats me. But it will be interesting to see how well it works.
You're probably thinking the band Sacrificial Anode would be some sort of heavy thrash metal outfit.
However, I believe they are a millennial Neofolk, otherwise known as Apocalyptic folk, acoustic group, championing EVs and the STOP OIL movement.
A bit like Midnight Oil, but more
Midday Solar.
Hence their total disregard to what damage is caused to the environment and people, in third world countries, to produce batteries for these vehicles.
Do your self a favour.
Probably not worth a listen.
I have a 1992 Subaru SVX without a single bit of rust. The aluminum bits under the hood have oxidized, but no rust. I have a 1977 Jeep Grand Cherokee that you can hear rusting when it's humid. One thing I don't understand is how truck buyers still put up with the lack of rust protection. My F350 was $85k USD. Nothing that cost that much should have more than minimal rust within a decade.
Cool car.
My 91 G Wagen rusted to death, my current 2016 FJ Cruiser has survived so far thanks to meticulous care but FJ and Tundra and Tacoma chassis are famous for rusting themselves to death.
This was the first Auto Export video I've watched in some time, and delighted to see the comedic schtick kept to a minimum. Please keep it going like this! You've got a lot of good things to say, but it's hard to listen and appreciate the point when half the video feels like it's tangents of insults and sex jokes and various schtick.
Need a bit of comedy to season the litany of deceitful unhelpful dealers and importers.
Rusty vehicles very much not a thing of the past. If you live in any salt belt of America. Car life span is not very long because they fall apart from rust. Cars only a few years old in the scrap yard. All the electronics fail way before that. And then the car basically disintegrates. Japanese, American, European alike. Same in UK. Cars only a few years old red rust and falling in holes. Even brand new unregistered vehicles with rust all over them. Exhaust pipes rusted out and falling off. Quick coat of cover all underseal. New exhaust. And her you go Sir/ Madam, enjoy your new car. I have owned three year old cars. Bought from new. Sills all rotting out. Wheel arches going. All supposedly rust proofed. Until you feed them a diet of road salt. Kills anything .
I live in the UK.
My 20 year old 460,000mile vauxhall combo isn't rusty.
Some people swear by waxes or oils, others with rubbery truck liner paint. Road dirt (grit and stones, and mud) + Salt + wet (even just damp air) = rust, it's only a question of the time. The sandblasting of the road will strip away any plating or coating.
The options are essentially to either make it out of stainless steel or composite, something that won't corrode in those conditions, or to constantly reapply coatings and keep it spotless between trips to not miss any spots, both visible and in drainage holes, frames, sills etc.
@@MrCheesywaffles the frogs do pretty well with galvanized bodies and arch liners
@@sahhull it's isn't rusty until you break them apart and see the inside
If they made cars that did not rust they would be out of business 🤔
Maybe BYD got some raw materials from LDV.
Yes - there's that.
In Sweden they come with only 5 years rust warranty guarantee. (Not 12 years) They removed this information from their webside also LOL. I think that says it all.
Hello There, I have read the couple of corrections but I still beleive your vlog was spot-on, great topic, good research (except HDG on cars) hope you follow on with more details. Regards.
Localised concentration cell corrosion can still occur between multi-plate panels around salt and water, electroplated or not.
I remember the cool new Datsun my dad got in the early 70s. After a few years we called it the rustmobile.
All logic and truth, as usual, John.
I have worked making things, took them to GB Galvanising, then picked them up again and installed them in various out door places so I am somewhat familiar with the process. I have never seen any indication that car bodies are hot dipped but I have seen videos of them going through electrolytic baths. Are you sure you have the right end of the stick.?
Hi, rusty cars are a thing of the past, I don’t see the rust I did when I was a kid so whatever they are doing is working. Saying that my old Cmax is going rusty but it is 19 years old!
Failing all this, buy a Stainless Steel car or wash it off and fix any damage!
Take care all M
@@markeh1971 Guess you missed the point of my comment entirely, eh.
One or both brake lights also an issue - pooping themselves.
Also talk of warping on roof or tailgate panels. Looking for more info on this.
I would not trust Chinese manufacturing to reliably produce adequately galvanized cars. See, contractors and subcontractors and even corrupt managers are always trying to cut corners to save a bit of money.
"cars don't rust away anymore" hahaha they sure don't when you live in the outback or whatever
Replacing rocker panels on
FIAT and VW got together in the late 70's to galvanise cars.
I had a 1981 FIAT in the UK in 1989. It was treated and the difference between my car an 1980 FIAT was very visible.
Japanese did not galvanise in the 1980's in New Zealand as they rusted badly. Some failing their first inspection at 18 months old.
Thanks and best regards from Egypt.
Now wait a second , I don’t live in the snow belt in America, no salt on our roads. I do remember when Toyotas started to be sold here in the early 70’s. Toyotas from that era absolutely were Rust buckets !
BYDs for northern climate will need rust proof coatings at the factory before being sold. That should add about $1000 to vehicle cost. Do not buy unless rustproof if you live in cold northern hemisphere
There was an issue with the Daica Duster in the UK. The initial batch was made in India. They forgot to use galvanized steel (India cars aren't galvanized). They had to be recalled.
Definitely 2 standards - One for domestic and one for export.
Bog Your Dreams
Great info as usual John!
Darn it I was gonna import Chinese cars with a couple of hundred thousand ks to sell cheap in Australia, but if they’re not galvanised….
Talking to a mechanic with a few years of experience on this dual cab model. did I say Foton Tunland ... said stay away the subframe is a death trap for rust just seen to many...
Loved the Eleanor Rigby reference😂
Ye not sure you've got this right! Last time I looked car bodies are dipped in sulphate primer, the main corrosion protection for cars. I think you are right this technology became standard approx. 80s/90s
I'd say the member that was shown on the right of the screen (the blue painted example) was not galvanised after it was bolted together as there is clearly blue paint that was applied before assembly. It would suggest it probably was not galvanised at all.
I have a 2005 Vito van and had a stone chip approx 2mm dia and rust right through resulting in a 3mm hole which would indicate that the coating does protect the whole panel.
Not all galvanisation is equal. Hot dip galvanised is the preferred treatment instead of cold dip or electro which is popular in India/China.
The best way to avoid buying a rust bucket car is to not by a Chinese car.
We had galvanising in the 1880's; I even got my Benz Patent Motorwagen done
About BYD rust problem, you can watch this great video about comparing BYD Qin PLUS DM-i VS Toyota Corolla Hybrid by a Chinese guy with English subtitles.
It mentioned about BYD rust problem in 19:36
czcams.com/video/UAi33Vneqgs/video.html
I was expecting this, but not to this degree so soon, this has exceeded my expectations. Not much better than salt water on bare metal.
Remember when I said your mate, the other car expert was telling everyone that this was a great buy?? 🤦
Seeing the brand BYD reminded me of a youtube video on the Serpentza channel showing the BYD cars bursting into flames and airbags not going off in China. Interestiong video. I also watched one of your videos on EVs and when talking to my sister in NZ she said that if you have an EV charging point wired into your house the insurance premiums skyrocket.
Even American cars get rust when you use it constantly near the sea. I had Ford explorers with rust, whilst I was workikg with a sea port operator.
Fear n loathing is a good strategy. They said this about the MGs also. It didn't work. The clock is ticking for ICE maintenance revenue.
12:13 No FKN way!? He works at a surf club and parks near the beach? Unheard of...which leads me to, I believe might have been one of your older videos where a warranty claim for rust damage was rejected because the owner of said vehicle lived near the coast.
Thanks
1970s .. buying a car with a pocket magnet ... seeing the magnet not attract in 70% of the Cars panels
I think BYD stands for Build Your Disaster.
Blew Your Dollars!
Bugga ya day
Buy* your disaster
I thought it was Beijing yearly disaster
Beyond your disaster
In the East Island of Australia, BYD is an Ateco brand, they don't seem to be owning up to that for Australia which seems a little odd.
I thought vehicle manufacturers I used E-Coat not not HDG?!
I watched a CZcams video on a brand new Toyota’s 79 series with rust under the roof lining and that say that see it all the time.
On a different note John it looks like I have managed to purchase the best quality 30 kg chinesium anvil
Even though they said they were out of stock so looking forward to it arriving in the middle of next month 👍👍
