- I was over at Ital Meccanica in Huntington Beach where my good friend Alberto Ferroni was doing some bodywork on his Porsche 911 race car. Here, he explains the benefits of using lead instead to plastic filler and how much faster the process really is. Don't forget to 'Click' and SUBSCRIBE!

Back in the 70's I knew an old black man that was an artist with lead. I guess I never knew his real name, we always called him " PICK - N - FILE " He refused to use Bondo. He told us if a car was really screwed up it could weigh 100 pounds heavier when he was done. Funny his grandson was an artist also, but with Bondo. LOL... Did it in half the time as well. I'm pretty sure the old man has since passed, but I do remember how GORGEOUS his jobs came out. R.I.P. " PICK - N - FILE... ;-)
What does him
Being black have to do with the story? Just wondering.
@@dw5878 Now that I think of it, not much. Except he was a really NICE guy, and I didn't know many black's that were as nice or talented. He WASN'T an angry man, and DIDN'T feel White America owed him shit. His grandson was just as nice. There are many black's that I DON'T feel warm and fuzzy about. He was a GOOD guy. I have pleasant memories about him. So there you have it. If more people were like him, we wouldn't have this BLM issue. My political 2 cents. LOL.
@@dw5878 it gives you the generall idea of the guy in the story. I like to imagine what te person might have looked like, so the fact that he was black, gives me material. Go be offended somewhere else
@@entrophany Nice reach there. 1st of of All wasn’t asking YOU anything. I was talking to the guy who made the comment. 2nd he didn’t say the man was black to add a visual to the story,. If that was the case he would have said he knew this old white man who was an artist with lead. People say things like that because race makes a difference to them. That’s what they notice. The mans race has nothing to do with the point he was trying to make.
And if someone said an old English guy, or an old russian guy or an indian or african guy that would be racist as well. Hey over yourself. The bloke said nothing bad about being black.
People need to settle down.
Dying art. Definitely prefer this method of body work on my 71 pagoda over bondo. Why anyone would use bondo on any vehicle that has a potential value of 6 figures when completed is beyond comprehension. These guys should start an apprenticeship program to preserve the trade skill. High value skill because not many are doing it or even know what it is.
I was taught to do lead wiping as we called it while doing my apprenticeship with Mercedes Benz back in the late seventies in South Africa we weren't allowed to use body filler we had to panelbeat using a what was known as a file hammer and then file it using a flexible body file and shrinking any high spots and if i'm not mistaken i saw the marks of a file hammer on his fender we used a different technique for spreading the solder not too different except we made different shaped wooden blocks for different parts of the vehicle usually teak and we also used ATF and later bees wax as a lubricant to help spread the wet/molten solder applied to the block before spreading it also prevented your blocks from destruction i'm happy to see that the art of body repair the proper way is being kept alive respect sir
Amen to that. Well said, Brother. RH DSD
never the proper way yet manufactures and repairers were doing it in the beginning? Steve share some of them drugs, or at least give an explanation for that shit you dribbled?
@@jasonstalder5208 Before there was bondo for dent repairs, way before you were born, this was the proper way.
@SpeedRacer 650 It looked like to me he stayed on the tinned area, just got close to the bottom edge.
@@sailingsolar i know buddy, my dad taught me to lead load and is older than the gentleman in this video. i live by the old ways. the tin of bondo in my shed is so old it cannot be used (thats how much i use it)
This craftsmanship is reserved for a vehicle worthy of preservation. Most modern cars however expensive are not built to last. Kudos to the maestro.
When I was a boy I used to hang out at a body shop to watch body guys do this. It takes a great deal of skill and knowledge to do this right. I loved watching this video.
Folks, he is using 70/30 solder like what is used on brass musical instruments. 70% TIN and 30% LEAD. There is nothing else in the rod besides trace contaminants. Having 70% of the filler be tin makes it much harder and more like steel. The 30% that is lead is strictly there to allow the tin to melt and flow. Electronics people frequently use 60/40 solder because it is softer and flows into small spaces better. You do not need the end product to be super stiff like steel on a PCB - you need two pieces of metal to have permanent contact with one another. On a trumpet (or in this case a quarter panel) you need the end product to be very hard, so the tin content is bumped up some. He is *not* using "lead" as some keep saying. It is tin/lead solder.
Still a dangerous mix. Pretty much any lead without sophisticated protection is too much.
Exactly.I was a panel beater in 1958 to 1968.We always used body solder with good results.Did not harm me at all.85 now.
@@DDS029Yes because the chemicals and fumes in other types of filler are sooo much better for you duh. People hear lead and right away want to put on hazmat suits you probably drinking worst in your tap water than the exposure using this method.
I used to melt 90% lead, 1.5 % antimony and 3% tin in a stereo room as a kid. Dross off the impurities and make ingots or as was called pigs. We were printers with Linos and news work. I added plus metal to keep the ratios constant. At 540 degrees things were a little warm at times. I kept taking salt tablets and water. Start drinking Pepsi and you could get dizzzzy. We had a body man in town and a new Ford car fell off the transport truck from the factory. This man used 6" X 1/2" square lead with oxy to fill in the bent fenders. I have used solder/oxy to repair a gas tank leak on a Mitsubishi car and it requires a cleaner to prep the metal for best results (the cheaper solder from China is bad news). This approach we see here seems rather slow; but, I only guess. The tin gives it hardness and the antimony allows the lead to fill in the tiny pockets. I would rather use a smaller torch head with the fuel being used here and thus allow the application to be heat and filler metal (simotaneously sp) with a more continuous motion. This would speed up the process and lay down a more continuous amount of filler. It can be done either way. I have seen the oxy approach and it is fast if you have the hand.
yes, its ok to sniff bondo fumes and kitty hair.
Watching this guy lead loading takes me way back to my apprenticeship ,part of which was accident repair, this was about the period when the modern body filler was just emerging, people here talk about the health risk with using lead , sure , but when the present day types of body filler came in not many people thought to use breathing masks , so it wasn't only the actual user that suffered , anyone working in close proximity were also affected,
I remember one old guy , he was a joy to watch , lead loading was an art , he always had a Woodbine smoking away in his mouth , great bloke , but what I did pick up on,
old Les used to shape the lead by using a mole skin covered spatula to which he would apply a very light coat of tallow, in those days it was just not allowed to use filler paste on the Rolls Royces and Bentleys it had to be lead , hey the good old days ?
When I was fixing cars back in the 1920s I was leading up a storm with solid lead
i just found out my grandfather did this type of work when he moved to the U.S.A. back in 1957 untill today i never heard of this kind of work im going to look more into this and thank you for sharing
Great video CM R&D!
I'm just getting started with building my first hot rod. I like learning these old school techniques that you don't hear much about anymore.
My dad did lead work and pick and file, he trained me. This was many years ago, thanks for the video and the memories it brought back.
Thanks for posting this, John.
Dude more of this guy and his little porsche.. Thats awesome technique !
Excellent instructional video, Alberto Ferroni looks like the classic European craftsman, it's a pleasure to watch him work. Thanks
That was awesome! Great presentation! I learned a lot. This makes me want to do leading. It's not really that bad once you learn it!
Absolutely brilliant! Now do it with the glass and interior still in and see how that goes. No wonder Plastic filler became so popular. But if you're doing a bare shell, bare matal resto, then this is it.
good point
I started doing Autobody repairs in 1957 the sheet metal on the cars of that era was substantially heavier ,and still you had to be very careful to avoid warping ,the cars of today could never take the heat without distorting beyond saving. True Bondo changed the whole industry.
Hi can you pls share some of your tips and tricks from your Automotive career?
Leading was a common practice in the factory back in the forties, fifties and sixties. utube has several videos showing this. but those guys were quick and very accurate. a lost art!
GM car plant in Oshawa was still finishing body work using using tin/lead in the 80s.
I had a '78 Chevy truck body that had some lead over a repair that appeared to be factory work. Eliminated the rust around the edges of the lead, and then re-repaired it the same way (lead).
Thank you John, this was amazing!
Always wondered about this, but it seems so right instead of awful filler/bondo
Nice to see a pro at work, repaired many cars using this process, still good today, keep it alive.
Don't worry about protective equipment. There was a canary off to the side next to the asbestos wrapped chewing tobacco and the leaded gasoline space heater.
Yea because there is not toxic chemicals in bondo and fumes
Give us a break, would ya?
relax, he wasn't chewing on the shit! lead gives off toxic fumes when its over temp and TRUST ME after 17 fucking years in the trade the isocyanate will get you 1st every time
@@jasonstalder5208 exactly! if lead poisining worrys you you probably should work in a body shop because frankly i dont think theres anything in there that wont fuck you up
paint fumes
resin fumes
exaust fumes
oils

other automotive fumes
sharp things
hot thinks
heavy things

ppe is helpfull but there comes a point where you just have to say fuck it and get the job done
cause if you go by the recomendations that soy latte drinking office boys will come up with your average roofer would spend half his time just setting up infact i think the current H&S requirements for reflashing a roof would be

My 48 Chevy has lead on the cab corners and the cowl and roof pillars .thanks for the video now I can do it the right way
Thank you for this John, I was lucky my grandfather taught me the art of leading a body. it is a dying art and not to many people left in the world that can even work lead. Great flashback here and great memorys of my grandfather yelling at me for getting the metal to hot ha ha. Excellent video Keep it up buddy
I'm a lettering artist/sign painter some crafts if they can't be altered to be safe, should die before IT kills anymore. Luckily the vinyl crap hasn't totally killed my craft, now that lead-free good quality lettering enamel is available.
love this video I'd love to see more of it
me to this is the first video I have seen on doing led work
I thought on modern cars the sheet metal was so thin that even the low temperature needed for soldering could easily warp the panel.
Leading in was common practice on decent cars back when I was a lad in the 50/60s.
Glad to see somebody still doing body work the right way
Lololololololol
When I was on a school trip to the Ford Motor plant about 100 years ago (might as well be) I watched a guy filling the join between the roof and the body with lead on a Mk3 Cortina.
Correct; they used lead fillets to contour those joints.
All cars of that era had lead joints in the rear dog leg...its a dying art lead filling/joining
I tried this once with my Reliant Robin. It didn't go well....
Ha ha ...
your meant to use a hair drier and Plasticine on robins ,,, lol
robins are a small three wheel car here in the uk , prone to tipping over , however the joke here is that they are made of fibreglass , lol
I remember a guy restoring a 1968 Oldsmobile 4-4-2 and he used lead instead of bondo (aka plastic body filler) for the body panel filling
Lol
nice work, really enjoyed this video.
interesting . have heard this term "leading" from many years of being around auto shops but never saw it done. very practical. no shrinking and becomes part of the structure. I like this. thanks.
that man is a true master of the lead
Thanks for making this video!
why are their 4 min of just black screen?
Im building a period chopper and this is how I intend to do part of the frame molding, along with some brazing and tig welding where the gas tank is molded into the frame neck. Thanks for sharing 😊👍
Fantastic this work , congratulations !!!!
this is a very good way to repair a old jeep body or other old heavy gauge car thanks for showing this
I worked at a car plant that received and repaired new vehicles shipped here from other countries. They had to use lead as a filler on some spots. I watched them do this every day.
I come from hearing about the lead sled days in Lakewood and Compton California car hop days. That was the filler back then, so I learned from George Barris and Junior Hersh Conway at Juniors House of Color. Now thanks to your video I can see the actual work that my dad and uncle talk about sometimes more back int he 70's and 80's and those 50's mercs
Alberto is an artist! A true lost art! Plastic filler is not all together that bad because it does have its applications. You can't do this to a painted panel and the heat does stress the metal.
Why would you want to
@@themechanicman3865for collision repair.
Lead is eternal! Fantastic work!
Awesome! well Done!
Brilliant 33seconds in and somebody remembers to plug Alberto in ,Great to see a skilled man at work,these days whole panels are Bondoed(fillers) before paint .what did they do to get a smooth finish on the old car,( lead?)
thank you for the demonstration. it was informative
in the 60s the shop ihung out had a pot of molten lead cooking I have some lead bars which I use to fill small rust holes such as hood where filler does poorly in weather you can patch w.copper then lead if large spot.
watch out, some fool will try to pour that molten lead over someone's head like in game of thrones, my girlfriend told me about that and got me hooked on that show lol
I just watched a Leading video & both yours & Eastwood's video opened my eyes.
I want do Bessie up with lead.
Aloha,
Chief
If you do lead work on a rusted panel with the rust come through the pain eventually after its leaded ?
Amazing artist! Don't know with Fiber Fillers today and the way you can fill with a hard adhesive as opposed to bondo, but would I always take the time?..but if I had the time and a Porsche sitting in my garage....hell yes...I would love to give it a try! Amazing hammer work to get that fender shaped the way it was to ready it for lead! That is so hard to do without stretching the metal as you flatten! So bravo...and then to see him work that lead like butter, is amazing! Certainly is a lost art!
The metal is already stretched due to the damage. The trick is to heat shrink it. That will take care of at least any kind of filler work. Lead, fiberglass, or plastic.
Thanks,enjoyed very much. I heard lead was also good for areas that flex a lot.
EXCELLENT! EXCELLENT! Thank you.
my grandfather just passed away at 71 he started doing body work 50 yeas ago i had the chance to talk to him about led its something that is a lost art in this part of the world was fascinating to see him light up and talk about doing led on cars from the 40s in his back road shop he built from reused boards and a dirt floor was in the building a few years ago its sagged and twisted probably going to get knocked down hard to believe he painted the better part of our rough estimate 6400 full paint jobs and countless touch ups
it's lead....not led
Thats awesome you got to talk to him about it.I'm sure that gave him so much joy,to share with you!Your grandfather was a baller!
@@roygray6674 7 years he's been gone miss him dearly
Good vid i like you keep it old school i never got to learn that im a body shop baby but unfortunately led is one thing i never met my dad works very old school and im happy i got to learn this trait never went to school straight to the frame lol
While I appreciate the time and effort someone took to share this with up, why do haters have to hate out loud? If you don't like a particular video, move on or make your own and SHOW us how much you know. Thank you for sharing this video. I would like to meet Mr. Ferroni as I'm sure he has some great stories we could all learn from.
Chris ,
Because everyone has a right to voice their opinion good or bad, if you dont like it thats tough shit.
well said, these people are called "trolls" they even hate the good videos don't matter what the subjects.
Body butter is traditionally a tub of tallow that is used as flux for leading. Since tallow and butter are very similar, and it looks like a big cube of butter, I assume that's where the name came from. I've never seen plumbing solder paste used for tinning the body, but it makes a lot of sense and it much less stinky than the traditional method. The only concern I would have is the flux in the the paste being corrosive if not washed off immediately after tinning.
+eformance the tallow part of this that it is the barrier between the leading bat and the body solder
Hotgoddamthatizsum beautiful utoob writin!
EFormance Engineering the sheep tallow is used on the wood paddle to keep the molten lead from sticking to it instead of the metal.....my uncle owned a body shop in Hamtramck, Michigan years ago I watched him perform magic with lead filler
There were different blends of plumbing solder
Hi. I am used to use, after the scochbrite, and wax/greaseremover , and after that amix of water and bakingsoda, to top up with . By the way, they call the paste "tinnbutter". The bakingsoda removes all residues of acid, on the surface. You agree?
Very interesting.
Is it possible to use this method also in aluminum car bodies?
Always nice to watch a pro in action! !😄😄😄😄
Wonderful craftsmanship that is a genuine privilege to watch. I'm told that before the seventies a lot of new cars used to come of the line with a surprising amount of leading already in place! Thanks for the treat.
Not sure if I agree. I know enough to be aware that this only demonstrated the application of the lead and the job is only as good as the subsequent finishing of the profile. For me it's the appeal of the craft in the initial application of the lead. There is no doubt about it being a better process than resin based fillers.
Mate! It is a dying art as the guy said and if what you said was correct then my father-in-laws career spanning decades never was, so I will take your heartfelt comments on advisement. You don't like it and yes you would not tackle an entire panel such as the one shown here but rather would reach for your leather hammers. I can assure you that the craftsman panel beaters of old used all these skills and more besides to turn out many wonderful cars. I'm sure that your experience is applicable to your world as much as mine. You have a different opinion let's leave others to work out who's the twat!
Steve Prince as I say , you have your opinion which is allowed I believe. I have mine, also allowed. You are obviously a god among men and I am ignorant. I am glad, however to be me and not you. Feel free to troll off to your ten figure cars!
Steve Prince that's wonderful Steve and I am really very happy for you. You must be most welcome wherever you go! In my experience, which you choose to discount based on no apparent knowledge, I have seen many piss poor old and new repairs both polymeric filler and admittedly rather rarely now, in lead and I have encountered many leaded repairs that have lasted the test of time without ever showing themselves till exposed by trauma. If I was conducting repairs to a valued car of mine I would certainly prefer lead to resin filler if I have to have either.
Your ego is most welcome to reply yet again if it wishes but to be frank, I'm so fucking bored now I can't be arsed to listen. Cheers
Steve Prince. Why would you care about the opinion of an ignorant, semi-skilled, inexperienced and half blind person. In fact, I have only one thing to be grateful for. I'm not a sad socially dis functional twat that has to hang around on CZcams to find people to engage with new! 😆
What is that spatula you use in place of a paddle? Where can we get, or how do we make one? Thanks for getting me started leading my ‘67 912
That man is a craftsman
When does it stop looking like crap though? wasn't a solid line, wasn't smooth, looked like puddles. Can it be sanded like filler or do you just have to live with that?
so glad u guys filmed this. i dont see hwo this is something that was fazed out. especially the fact that its structural repairs while bondo is just a band aid to hid the bad stuff.
That's amazing! Thank you!
A true craftsmen at work :-)
Very cool I might give it a go with some scuffed wheels I have. I also wonder if you could use lead free solders instead they have a higher melting point but that may not matter for this application.
That’s cool. In roofing we use a similar method with copper. A soldering iron is used. Some have a torch attached. I do sheet metal work( metal roofing, ductwork etc).
Instead of a Bondo Buggy, you end up with a Lead Sled
Is it possible on vertical surfaces, must be something that takes practice . Considering it for my truck fender flares.
its good to know the old ways. thanks.
If in a area of the vehicle were it's impossible to use a torch you can use a soldering iron I did a lot of this work in the 80s but I must say plastic filler is as good if done correctly the biggest mistake most people make with any body filler is they make it to thick no filler should be over one eighth of an inch thick
insulman100 I
This is very much like how I do it, I leaned myself just by trying but it was mostly a no brainer since I have been doing electronic soldering for most of my life often using a torch for large electrical connections.
Also on a side note, I saw a 930 at the blasters recently and it had old pre existing lead work in the same areas in this video.
I wonder how you add more without messing up what you've already smoothed?
Obviously a better end product. However do EPA regs cause this to be an issue?
I was taught by an ex Fisher Carbodies lead loader, and I did it for many years. Two things: I never used my finger with the solder paste, but a clean brush, and secondly this an active acid flux and after tinning it's essential to rinse off any residue or you will get crazy rust. We made a hardwood bat, like a little boat, which we kept in a hubcap with some clean oil and a cloth. You can do any shape with one of those. By the way, when car bodies got thinner in the 1980s, believe it or not we had an asbestos mash mixed with water that you put on the body around the lead area to keep down distortion.
My friend a I rebuilt a 1944 Willys MB and that how we did all the panel joints on the patch panels. Did it 6 years ago and their still solid. It was daunting at first but really was a lot of fun. We did it in an open air and all filing was done by hand. Power sanding doesn't really work like it does on bondo. The filing really does smooth out easily. Go to Eastwood for supplies, they are great.
The rest of the fender is going to need filler it looks like a sack of walnuts. Don't even try to tell me he leaded the whole panel. The "real" proper way is to replace with new panel and lead the seams.
If "proper" you mean someone seeing it later in time that it was a period proper fix, then yes. Kind of. But when using metal to close up the hole in the roofs of cars from the twenties and thirties in the fifties or sixties, large areas like the part below the lead, would have been filled and block sanded with many coats of primer. of course after some more hammering and heat shrinking.
I have skimmed whole panels with it and you just disperse the heat, work faster and use a larger paddle with tallow working from the bottom up but by to days demand for finish nobody can escape a fine skim of epoxy or glazing putty.
Thanks for the update, nice work! Take care.
On high value cars 'originality' is key to keeping the value, even replacing damaged parts with oem/genuine parts will knock off a huge chunk of value vs keeping and repairing the original panels.
I was thinking the same thing.
it's always nice to watch master craftsman dong what they love to do.
I did it on a motorcycle fender about 10 years ago and it was fun.
Haven't tried it myself but I'm told you can use an electric hot air gun to give a very "soft" heat source.
you'd be there forever..
i didn't read the description....but after the first two words from Alberto i thought "it's Italian, for sure!"...... i guessed XD (Greetings from Italy!)
old school skills. best cars start with the best metal work. my brother is old school panels to, the go to man for prestige work. he did my toy , full metal finish with a little lead loaded into those "bad spots" for future cancer protection. car always gets comments about its lines. hat off to you Alberto!
I had a 1970 ford fairlane 500, when the viral top went bad I removed it only to find the factor had leaded the roof panel to the fender, I didn't realize they were still doing that at the time.
Is there a similar process for alloy wheels?
wooden paddles and beeswax when I was a kid and dutch boy tining compound.
"...when they took the mercury out it didn't work good" (Bill Hines at 1:03) LOL! czcams.com/video/jQ_85fp1avs/video.html
I can see where both leading and body filler have their places. As for people talking about the weight of body filler don't be absurd. Lead is incredibly heavy and the shade tree forma panel body filler way of doing this isn't how it's done. When fixed properly there is never much filler involved.
Any source for the lead solder and tinning flux used in the video? As for safety a proper respirator face mask and face shield are a must as well as a fume extractor similar to the ones welder use. I don't see any problems. One can also use thin leather gloves if you are paranoid about handling the solder. I would much rather have this type of repair on a body panel compared to bondo. I have seen complete patches fall off of fenders if flexed a bit too much.q lead won't do that. Proper restoration of older classic cars is most often done with lead since it is more of a permanent repair.
Please ask Alberto if he ever worked at the Body Shop at the NATO Navy Base in the Baia area of Napoli?
Much Appreciation
Much Honor
Lot's of kids here watching this, judging from the comments. If you are a naysayer to this technique, you should know that lead becomes a shapeable, bendable part of the metal, unlike a poly filler, that locks you into the final shape. Not only do you not your tools and metal, you don't even suspect. But then, kids don't get paid to work on cars like this.
Not only what?
"know' is the word here. Digital communication can be a bigger beast than metal work it seems.
Yea, lead cracks over time, you can see it on 60's MOPARS around the A Pillar with regularity, but lead moves with body torsion better than a plastic (Bondo). Why someone doesent believe lead bends is just besides me. Your typical fishing weight doesnt crack when you squeeze it with some pliars. Printers lead cracks easily, but basic car body lead does not crack until it oxidizes for a looong time.
Does 95/5 work for that too?
Best video on lead work
What kind of paddle are you using?
What’s the brand of the flux paste?
Very good!
in my time we used a different spoon for doing that . I used a lead spoon and a vixen file.
Ever wonder why they called hotrod 50’s Mercury’s “Lead Sleds”, here’s your answer. They were all leaded, all the frenched headlights, tall lights, shaved door handles and trim, all of of it was done with lead.
I grew up in Amityville L.I. N.Y. . When I was about 5-6 years old I d walk up our street ( Margaret’s Ave., ) to Tony’ Auto Body Shop , Margaretta & Old Sunrise Hwy. Tony Wojehkowski did lead ( only ) body work using a lead hot pot and a shaping trowel . He was a master and always had 3-4 cars needing work . 10:40
Omg this brings back so many memories. My father was a body and fender repair guy most all his life and wiped lead back in the 50 & 60's. Use to watch him squish the lead rods and make puddles and then working it with wooden paddles in acid that had different shapes and sizes.
He would be 98 now if he was still alive. It is a dying art that the new generation never learned but the metal of today cars will not stand up to the heat without warping.
Like Stuart Cambell we also used to call it wiping because our method of application was different. We would have a container of liquid white metal (same as you rod plus a bit of zinc). We would wear a very thick leather glove with an attached thick leather flap. You would plunge your gloved hand into the molten metal and then wipe it off against the area to be repaired. Done very quickly to avoid being burnt.
used a piece of leather , a 'moleskin pad'
Ok since there seems to be a lot of misconception, here's the answer straight from Icar, lead is no longer used as a body filling technique as it is most importantly dangerous, the inhalation of lead dust is almost unavoidable, also the common misconception that the leading process adds structure, when in actuality the wide difference in density and material thickness can negatively impact structural integrity and balance of a panel, far more than more traditional methods, also depending on the type of base metal lead can promote corrosion. There you go straight from the horses mouth. In my experience, if I get my hands on a panel and find out its been leaded, when I check it, the whole damn thing ends up warped, I've been told by the old guys its cause over years with the vibrations and other forces on the panel fuck with the lead and it will pull the rest of the metal in all sorts of weird ways. Most importantly these guys say we stopped using lead because we can get better repairs without it.
But they don't use lead, it's a tin alloy. They stopped using lead decades ago.
But still : Depending in the alloy used, corrosion could be promoted (i.e. Electrolytical Corrosion. The same principle why you mustn't use brass couplings on steel pipes.
I've actually seen some lead under a vinyl roof on a car from 1970. It was factory but it all crumbled as the roof was peeled off. Some guy came in and redid it. All he did was scrub it with a wire brush, reheat it and touched it up with a thick solder stick like they use in radiator repair shops. Took about 15mins a side and he used very little of the stick.
@@ThePaulv12 They used to use to use lead on production cars probably up till the 60s or 70s, particularly where the roof would join the pillars. I think they also used it to combine smaller stampings to make quarter panels. I remember in the mid 70s there was a GM commercial where these cars were going down the line and this guy was applying lead to the pillars almost like someone applies plaster to drywall. The guy had a steady hand and was doing it fast. Back in the 70s when vinyl roofs were all the rage, I am guessing that they probably cheated a bit on the quality of the job if they knew the roof was going to be covered in vinyl.
GM used a type of Hot Melt glue in/on the Monte Carlo C pillar seams. No need for finesse when it will be covered with a vinyl top. Non-vinyl top cars still got the lead filled seam. But then,how many '70's Monte Carlos have you ever seen sans vinyl tops? Few and far between!
You can tell he's an old school Italian guy. nice job sir
