Well if the Head cracks, just repair it with JB Weld
Great point!
or super glue..... I made a cylinder head once out of epoxy and sawdust. Lasted 22 years.
12cm LongTimeLove no fucking way.
good choice of words Mateo.
@@ProjectFarm now its time to make one for an ohv engine :)
If JB weld needs advertisement, they seriously need to use this guys youtube video. This guy just made JB weld sales go up, give him royalty checks lol.
Thanks for the positive comment.
Calling you out JB weld
agree..
JB weld does need advertising :/. I guess the manufacturers figure jb weld is so good, they don't need advertising for jb weld. Either that, or the manufacturer doesn't want to bother with advertising. Either way, I agree that they could use they if they wanted through project farms permission.
This guy has made me a JB Weld customer for life.
Wow - I never would have believed it. Thanks for the video! Suggestions:
1. Show us the inside of the cylinder head after a minute
2. Run it until it fails
3. Fix the failed JB Weld cylinder head with JB Weld, and repeat!
Thank you for the video idea!
And if that J.B. Weld repair of the J.B. Weld fails, fix that also with J.B. Weld.
yeah, not doing #2 was a bit of a let down
@@ProjectFarm Still waiting for this gem in 2020
I was really expecting to see the jb weld cylinder head getting destroyed. Please do no.2, run it till it fails but be safe.
"With a ratchet you're most likely to keep it straight." Proceeds to do the tower of pisa stance.
Glenn haha i was thinking the same
This triggered me hahaha also why didn’t he show the cylinder head afterwards.. pitty. Awesome video though!
@@combomaster99 You can see it behind all the links at the end for about 5 seconds.
I was thinking the same thing.
Right!!! I’m looking at that tap like bro it’s crooked as fucc!
Aww. I wanted to see how long it ran total before failure and I also wanted to see inside after the test to see the damage or lack of.
at the very end it shows the damage 9:49
iawindowss
Too hard to see under all the annoying links...plus, idk enough about such things to be able to identify what's damage & what isn't, I'd need him to point it out.
@@Lady8D Ya it is hard to see
Well telling by the condition of the head surely under 5 minutes it would've lasted.
Right? Google tells us JBW will last at 600F for 10 minutes so not surprising it lasted for 1.
Actually surprised it ran at all. Not because of the jb weld, but because there was no ground for the spark plug. It just so happened that the gap between the plug washer and the head bolt washer was close enough for the spark to jump, can see it arcing while its running.
FireAndGasoline, Yes, I placed the washers very close together, but not touching. For the conspiracy theorists, this provides proof that I'm using a non-conducting product. Thanks for watching the video and commenting!
FireAndGasoline good eye call on the washer arcing. I would bet money that was luck on his part. He probably didn't think about the plug being grounded. Never mentioned it.
I noticed the arc right away, then realized that was the only reason the motor ran at all
The ground path for the plug was probably my biggest question.
This is awesome! Also I was hoping you would test it to failure or at least disassemble the engine to see if combustion was chipping away at the epoxy.
Hehe... that washer-to-washer "ground" is sort of a built in spark plug anti-fouler...
Brothers Ford f150 intake manifold coolant passage cracked on a road trip, fixed it with JB weld and it made the 400mile journey back home and even did some errands around town before it broke again. Jbweld can fix anything, even a ford
Impressive!
Matt McAvay Go watch my boy sexyshooter0510 he is new to apex and needs your help to get big!!!!! Go watch his clips
My dad has fixed a cracked block once with JB weld when he was younger, lasted at least a few years after he sold it.
The easiest way to fix a ford is to junk it and buy a Chevy
Dude nothing fixes a Ford it's just temporary repairs
I'm amazed, I was expecting a "that's a lotta damage!"
Thanks for sharing.
You can get away with adding metal powder up to 1/3 of the volume of the epoxy. That both makes it stronger and better at dissipating heat. Cast it so i has fins like the original cylinder head, but taller to account for the worse material, and i think that thing would probably mow your lawn before it dies.
Anders Juel Jensen I’m not sure what the recipe is but I think JB weld probably already contains metal powder, either iron or aluminium. Or both. It’s good stuff.
it already does obviously but its cheaper to use epoxy than metal for mass production
how do you figure that it's cheaper to use epoxy than metal for mass production...?
On what planet is epoxy cheaper than metal? It certainly isn't Earth
MrcabooseVG
To be fair it would probably be cheaper to manufacture. No high temp furnaces or machining. Just casting.
Just build a whole engine out of jb weld xD
Jama tut, LOL! That's way beyond my skillset but I know there are others with the tools and skills to do this. Thanks for watching the video and commenting!
Project Farm Thank you for making these great videos. I also have a "real" video suggestion: Put WD 40 into the gastank or Alcohol. *Spoiler* produces big clouds and flames xD
Jama tut, Great suggestion! Thanks for watching the video and commenting!
I was thinking, What if after you made the head you then coated it with a layer of a metallic substance to protect it from burns, like an aluminium foil barrier only a little thicker.
The bunk of the head needs to be kept cool so some fins are in order.
If JB Weld sticks to aluminum foil, just the foil would be enough. The thing the foil would be doing is keeping the burning chemistry away from the epoxy. A thin layer would do that perfectly well. Thicker metal my pop off the surface as it heats up.
You have singlehandedly assured that JB Weld will be around for another 50 years. This was incredible and this coming from someone who remembers when this product hit the shelves. Everyone should have JB Weld in their tool kit and in every car or truck you own.
Thank you!
This is honestly how Subaru build their motors
lol. Thank you
I'm not sure if that's an insult or a compliment! LOL
That's the secret to the EJ257, the piston ringlands are really cast from JB Weld!
:/
Whole heartedly!
Run it until it blows!
kyleflicker its the American thing to do😂
If you touch it and dont destroy it you arent a real american!
Take Israel back from pretend Palestinians.
That's what NASA does. Leave the safety stuff to the rest of us.
TakeAmericaBackfromISRAEL your worried about Jews. Lmao you know aliens are real so stop worrying about Jews
I honestly appreciate the time and effort that you put to make these great contents.
Abbas Sadeghi Bajgiran, Thank you for watching the video and commenting!
I discovered this channel about a week ago and can't get enough of your videos. It's amazing what you're able to do - entertaining and informative at the same time, with no BS. Keep it up, good sir!
I'm watching and realising you hadn't thought to earth the plug and I was surprised when it fired up but could see it arcing to one of the head bolt washers.
Yeah I was wondering how it was firing when he fired it up because i was thinking the same thing lol
Haha somethings just work out, he might have been scratching his head for a minute trying to figure out why it didn't work if he didn't have to add the extra washer.
My dad thought this was fake until I showed him this comment 🤝
7:50 did you see the spark between the washer and one of the bolts
The spark plug had nowhere to ground! Thankfully that other washer was close enough to complete the circuit
@@JonLarzon how would you even know?
@@alkoia it wouldn't be arcing otherwise
Sry I am watching in 144p
Who ever liked have a great life

Can you explain WHY no sponsorship? Im a man of God myself, but dont see anything wrong with that.

"I like to use a ratcheting tap piece to keep it straight..." it's as crooked as a politician.
No shit, that is way crooked.
its the way you hold your head looking at the screen
@Kenneth Boyer its not you can see on time lapse he turns it to straight...
its all perspective....i prefer to see it as straight as a rare politician
Doesn't matter, he screwed in the spark plug crooked as well, that will even it out xD
JB Weld for gas tank cracks, is beyond phenomenal !
Gas or diesel, steel, or plastic tanks, JB Weld has my vote, and has saved a number of my customers $100's of dollars ! Can't say enough good about it !
Thanks for sharing.
I overtightened and cracked a temp sensor fitting on a 99 mustang GT intake. Fixed with jb weld. Still no leaks 3 years later when I sold the car.
Impressive!!
i have a '74 Jeep CJ5 that previous owner had the motor rebiult b4 i got it. there was a crack in the block just under and back from where exhaust manifold connects to exhaust when looking from side. it would weep a little coolant, but not an unheard of issue. year two of my owning it, i got sick of seeing it so i ground it out just a touch with a cutting wheel, filled it w/ JB Weld and smoothed it over b4 repainting block....that was 16 years ago, has never leaked since and i need a strong light and magnifying glass to find it.
good stuff!
thanks! I needed that comment!
It looked like you were getting arcing between the washer for the sparkplug and one of the cylinder head bolts... are my eyes deceiving me?
Caleb, Yes, I placed the washers close enough together to allow the spark plug to be adequately grounded instead of running a wire. I thought viewers would enjoy the light show as much as I did. Thanks for watching the video and commenting!
yeah at first I thought that was combustion gasses leaking from the sparkplug hole but then I realized the plug needed to be grounded
Caleb Sandersier ya I seen that
I seen it to good eyes Caleb
Came here to comment about the plug, saw it was already addressed. Good job internet.
I would run a ground wire to the plug next time. Your spark, while present, isn't good enough to get proper ignition. The engine had several moments where it was running rather rough. With a proper ground wire ran, this problem will go away.
What is this gentleman's background? His methodical common sense approach is just 100%. So impressive to watch.
Thank you!
I just used JB Weld to repair a hole in an automotive seat mounting bracket to avoid welding. It worked perfect. Great demonstration BTW Always enjoy your videos!
Thanks and you are welcome! Thanks for sharing!
If you had any qualms about the bolt hole that was misaligned, you could always build it out with more JB Weld.
Great point and thanks for commenting.
In the Army we had a proprietary form of Epoxy with shreds of titanium in it for strength. We used it for repairs on the engines of tanks, APCs, trucks and just about anything else that required that the repair endure immense amounts of stress, such as a 427 blown Chrysler Hemi Diesel crank bearing housing in the back of the block. One enterprising young feller even made a barrel for an M-3 grease gun from it, and it did yeoman's duty for about 6 magazines. We decided that he'd proved his point and I personally destroyed it.
Thank you for commenting.
Why?
There is a hemi diesel I’ve never seen one
Sureeee a hemi diesel, stfu
Hemi is a gas and that don’t make it in diesel any one who knows anything about dodge would know this
JB weld is pretty good stuff ! I had a 2000 E-150 with a coolant leak. Its a "dealer only" part in an extremely tight space(entire intake manifold off to fix correctly) that was leaking right where the part(just a threaded pipe) screws straight down into the block. I 1st tried RTV silicone, just glob'n it all around the base & spreading it with a fat wire bc fingers couldn't even really reach all around it. That lasted a few weeks. the 2nd time I tried an epoxy putty & that only lasted a few weeks. The 3rd time I used JB & its still holding after nearly a year.
Impressive results! Thanks for sharing
Wow .The dedication that you put into your projects and testing is absolutely amazing. Thank you
You are welcome!
I found this channel this morning I've been binge watching all of the lawn mower videos🖒
gunnuts82, Thanks for watching the video and commenting!
Can you show the damage to the head after 5 minutes in another video?
He did at the end.
Years ago I got convinced about JB weld when I watched a guy repair an aluminum AC condenser with it. Great Vid I watch your Vids all the time.
Thanks! Thanks for watching!
When I was a kid, I bought a broken CR125 dirt bike for $100 because it had a huge hole in the side of the block a little larger than the size of a quarter from the motor bottoming out on a larger bolder rock. I was only 13 years old but had a lot of experience from doing stuff with my dad. I used JB Weld to fill the entire hole and then a dremel to shape it perfectly. Never leaked oil and ran great for years and then sold it for $1,500.
Nice!
Love your videos! They are so educational and entertaining!
RealTimeRT, Thanks for the positive feedback and thanks for watching the video!
Project Farm No problem. Keep up the good work!
maybe you should drill a hole in a piston and try to fix it with JB Weld. Wouldn't that be a great idear? :D
DennisMeier911, Great suggestion! Thanks for watching the video and commenting!
Im starting to see no end to this experiment. How many holes can be fixed ?
Maybe a new hole in a motor every week until it cracks open only to JB it back up again :D
ProCactus build an engine out of jb weld
My dad once had a car that blew a hole in the piston. He JB welded a 50 cent piece over it and got another 20,000 miles out of it
Your dad is a mad man. Sounds like a swell fella.
You are impressed with J.B. Weld and I am impressed with your ingenuity. Thank you for your public service
Thank you
Creative videos like this one are awesome yet still informative. Very fun to watch the well detailed build process. Keep up the good work.
Thank you very much!
this guy is a legend
You did not provide an electrical contact between the spark plug's thread and the mass. So you can see sparks between the big washer and one of the head's bolt - some part of ignition power wasted there. Aluminum is a good conductor, JB Weld - not.
Thanks for commenting. I meant to have the washers touching, but they were just close enough to work.
Ever use aluminum jumper cables? Aluminum is NOT a good conducter...try copper
Aluminum is fine as a conductor. Copper and silver are better, but there are tens of thousands of miles of aluminum transmission lines in use.
I saw that too. You could see the sparking between the washers brightest when it misfired.
@@jakemclean7563 aluminum is a great conductor and way lighter than copper. Some airplanes use aluminum wire for weight savings.
I used JB to fasten a cooling hose in the manifold of my 4.6 Ford truck. It has ran tens of thousands of miles. Great stuff!!!!
Thank you!
I have to say, although this video is three years old I think it's the best video of all times. From scratch you've made a freaking head that worked, man that's bad ass. This video goes as #1 in your hall of fame of all your videos. In fact, I think you should get your viewers to judge what videos should make it and why. Just a video idea for you to kick around. Yea, you have my vote and why on this video being #1 in your hall of fame of best videos, this one is bad ass I tell you.
5:05 Caveman CNC machine! I like it. I bet you had about 30 hours worth of work to make this video. And it works!
Tyler, LOL! Yes it is! Yes, I had a lot of time invested in this video! Several hours of video footage too. Thank you for the comment and for watching the video!
Tyler Clemens oh yes do i remember my dremel a 90 dollar pos only usefull for certain tasks i dont regret getting a hand held die grinder
Hi
Good job, glad it ran so well !
ChargerMiles007, Thank you very much! By the way, I really like your channel! Your craftsmanship is phenomenal!
Brilliant vid. Since I saw your first JBW test, I have repaired Land Rover body panels with it and today I plugged a crack in the grip of a cheap handheld spot blaster. Definitely a toolbox must have - thank you. 🙏
Thanks! Thanks for the feedback.
Impressive! Great job making the head!
I wonder what JB Weld thinks about this?
macnutpro13, LOL! I wonder about this too! Thanks for watching the video and commenting!
J.B. Weld and Seafoam both owe you big $$$! XD
They are laughing to the bank.
802 Garage Agreed!
I would hope they send you some JB weld .,they likely won't comment,but they should,your always going to have a few idiots. Project farm built a cylinder head,so I'll make wheel studs and save a ton of money,I broke all my wheel studs on my front hub on my 2017 911 Porsche,I used JB weld to make new studs,I'm now in the ICU center at Mather Hospital.JB weld you owe me 1 million dollars LOL
I was wondering how you were going to ground the spark and then I saw it arcing to the head bolt for ground
Daniel, The washers weren't quite touching, which resulted in the "light show". Thank you for watching the video and commenting!
I've never used JB Weld but after your two videos on the topic, I love JB Weld and will be using it in the future.
Thank you very much!
This is a nice throw back to when you were just a small channel. You've definitely earned all of your success!
Thanks!
That was awesome experiment.
Thank you!
I have used JB weld for alot of years and love it, If they dont endorse your video something is soooo wrong!!!!
Thanks you! Happy New Year!
It’s a completely absurd idea, and I watched every minute of it! Thanks for all you do
Thank you for the feedback
I know this is an old video but it reminds me of a JB Weld story. In the 80s a kid I knew broke some teeth off the ring gear in his 65 Mustang. Well, having a lot more time than money he took the ring gear out of the axle and washed/decreased it and formed up some teeth out of JB Weld. After it dried he used a dremel tool to cut them to the same height and shape as the originals and put the whole works back together. I told him 'That Shoot(or something close) ain't gonna work!'. He drove the car around the block a couple of times before it broke! I mean Yes it broke but it was pretty impressive that it made it that long! I love all of your videos. This channel is 10 times better than anything on TV these days!
Impressive results!
Love the hard work and dedication you put in your videos keep it up
Thanks, will do!
You are an extremely clever guy. I watched you very carefully how you did different tasks and you're totally professional. It's nice to know and also from the point of mechanical things, of course, we should always use them within the parameters for which they were designed. What you have shown is that amazing things can be done and motors can survive an awful lot. Most people I know, never change the engine oil in a mower. Just think how much hassle the engine has to deal with, with owners like that. You asked what kind of additive you should test since you are very sceptical about them. I'd like to see Ceramizer tested to see if it can really repair scores in bore or piston and to what extent can it do that say with a very old engine. How far can it really restore all the old wear damage, the light scoring and so forth?
Well done. I like your videos! I used JB weld to fix a crack on an OMC outdrive and it worked great. Sand away the rest and paint over it and it’s so solid.
Impressive repair!
Impressed with both the JB weld and his work of art.
Thank you for the feedback!
a month ago you had 4k subscribers. I looked again today and you have almost 20k! keep up the great work. I love your videos! glad I can say I was a subscriber from the beginning
Shaun, Thank you very much for the encouragement! I'm having a lot of fun creating videos and interacting and learning from commenters. I'm excited about several upcoming videos! Thanks again!
Project Farm I seriously can't wait to see where you are a year from now. hopefully making money on CZcams doing what you love!! if you aren't. ALSO, I know this would be a lot of videos and take a little bit of time but I read about top tier fuels being "better" for your engine as opposed to non top tier. because of this, I started using Shell Nitro 93 octane fuel. just curious if there is any truth behind that. I think it would make a good mini series!
hard to test fuels on a mower, they arnt fussy, the mower will run fine on 87 octane, so will most cars, 93 octane isnt needed on most cars at all. it wont do much for the engine, but sure shell might be using other additives that are better than another brand, more cleaners etc to prevent varnish, but that would take 10ks of miles and a control to know, certainly here in the UK supermarket fuels are always having issues with contamination but not so the major brands such as shell/esso etc
Jusb1066 I'm sure the 93 octane is aki and not the American used Ron index. 93 for him might be migrade in America.
I still agree with your point though. Lawn mowers don't care enough. I noticed I get poorer gas mileage from Chevron. Less additives means going farther per tank. lol
Shell has similar gas mileage to cheap gas. I'm more confident with Shell's research though.
Amazing experiment, I was hoping you were gonna run it until it broke and/or show us the aftermath. Keep those videos coming.
Siniestro, Thank you for the comment and for watching the video!
Siniestro Siniestros The aftermath is at the end of the video. I really like comments. They can help us if we missed something. It's a very brief picture at the end.
I'm never disappointed with PF work.
Man deserves to be a Millionaire.
Thank you very much!
I have to mention after watching this with my Son today and if the large washers were not used between a head bolt and the Spark Plug, the engine would not have run.
It’s important to know that the Spark Plug depends on the metal cylinder head threads for its ground.
The solution if ever doing this option, if needed, is to use connect a piece of wire between the Spark Plug and a head bolt that connects to the engine block. 😊
Thanks for the feedback.
Hello PF,
The various tests that you’re conducting are very basic by design but pure genius in the well thought out way that you conclude your test and present the amazing results. What you’re doing could be called a scientific art form for the logical mind.
You explain every step of your project in a way that even the self proclaimed web experts should be able to understand. And above all else, on the rare occasions that you make a mistake , you don’t hesitate to mention it and that speaks volumes about your integrity.
I ran across your ingenious activities by chance while browsing through this sea of brain dead geeks doing silly things to amuse their simple minds. Now I’m having a difficult time attempting to move on to anything else. Your projects yield results that can used
Thank you very much for the positive comments!
Eventually, an entire car from JB Weld...

Was using jb weld
Years ago. A guy with
A caterpillar dozer jb
Welded the block, when it
Cracked in cold weather.
Worked fine for years.
Great product 👍
JB Weld is great stuff. My dad rebuild a steering box for a tractor with it once and I fixed the coolant overflow tank on my dirtbike with it.
Impressive!
I bought a Honda XR500R dirt bike cheap where the engine case had been cracked and repaired with JB Weld by the previous owner a few years before I bought the bike. On this bike, the engine also serves as a stressed member of the frame. I had it for 5 years and never had a problem with it and later sold it to someone else. That proved JB Weld's strength to me.
Thanks for the feedback.
You seem like a genuinely great guy and your reviews/ tests are hands down the best scientific tests on CZcams
Thank you very much!
First of all, I love what you do. You're one of the most informative channels on youtube....... I just wish you'd have run the head until it failed. I'm curious to see how long it would last.
Thank you
I've seen jb weld perminantly seal a cracked sbc 350 from frozen water Crack. Still going after 4 years daily driving... Seen a Honda 50 dirtbike with a hole in the crankcase last for at least 5 years. Repaired a leaking radiator with it as well. This stuff is seriously tough man! Thanks for your hard work, absolutely incredible
Impressive repair!
Wow ! That was amazing. I knew JB weld was really tough. But that was amazing. A great idea.

It would have been interesting to see a long term test with this. 5-10 minutes running, multiple cycles cooldown cycles (we'd take your word)
Thank you!
@@ProjectFarm odd canned response but I appreciate the effort to stay connected on a big channel
Would have liked to see how long it would have lasted! I also was curious as to how you made that spark plug work considering they usually use the metal they screw into ALSO as the conductor of the negative polarity of the power that make im them spark. Did you achieve that through those two adjacent metal O rings that sit on top of your homemade cylinder head, one of which sat around the spark plug? (BTW, is an O-ring the same as a washer?)
If you rewatch the video, you can see the washer under the spark plug is sparking across the washer held in by the head bolt, that's how it's working. Not exactly safe, but it works.
oh sweet glad to see you took my idea seriously im surprised and very pleased to see the out take on it
Thanks for sharing your idea.
This project made me smile !! Nice work ! :) Nice way to start the day
Glad to hear it!
Well, I'm sold on J.B. Weld! :D
David, Thank you for watching the video and commenting!
Very nice! Maybe consider trying a beefy PLA 3D printed cylinder head?
Keegan, Great suggestion! Thanks for watching the video and commenting!
pla is far to weak. but lulzbot makes a bronze/pla infused filament that I'm sure with 100% full density settings and maybe a later of jb weld between the filament tolerance gaps it would perform well. it is very strong and if lightly shaped with a blow torch and polished looks pretty Damn cool
PLA wouldn't handle the temperatures. Tho it might run for a short bit. I've seen rocket motors made with PVC pipe as the casing which were quite successful but they only burn for a few seconds tops and the propellant burns from the inside out which keeps the heat off the casing until it is about burned out.
Keegan Thomas PLA starts to melt at 100°C so it wouldn't last long
It’s a crime that this video is not sponsored by JB Weld
Love JB weld and have for many years.
Great product! Thank you
why just one min why didn't you let it run for long btw you should have checked if engine is overheating with this head as this won't be a good conductor of heat and due to bad heat transfer engine could over heat
Wide open throttle, Great question! I don't wan't to hurt this engine. I need it for future videos. There's no way for JB Weld to disperse the heat. I don't care about the JB weld as much as I do about safeguarding the engine. Thanks for watching the video and commenting!
Project Farm What about milling some fins for a heat sink? Not asking you to destroy the engine, just monitor the temperature and end the test when it gets to a certain level.
+Stacy Smith Curiosity has killed the cat. Protecting the face may not be adequate even with the protection he used.
In the last seconds of the video look at the condition of the JB weld..... I don't think it would last another minute.
fins wont help, jb weld doesnt conduct heat like aluminium , its gonna get so hot in there to damage the bore/piston, which is why he stopped it, fair enough, we know something gonna fail, jb weld did what it needed, lets enjoy it
would double like if I could! thanks for taking the time for this experiment. if I wasn't already subbed, I would be now!
JB weld is amazing stuff.
Hand my sled chew up a ring and pitted the head. The local power sports repair guy. Buffed the high points of the pits out of the head. Then he filled on the low points with JB weld. Then buffed again so it was smooth. I was very sceptical of this repair
But it was a much cheaper fix then buying a new head. He also guaranteed that if it failed he would rebuild the engine with a new head.
Well it's been 6 winters and about 4,000 miles and no issues. Made me a believer
Thank you!

I don't know if it was already suggested, but try it with "Belzona 1111 Super Metal" also a very good epoxy material
Manuel Lagast I was going to say the same thing. Hold on to your wallet tho! Do not breath the dust from Belzona! It can kill you! Good stuff!
6:22 I like this technic bc you can keep it straight. Doesnt look so straight to me :D
Years ago I had a tiller that had a tree limb fall on it braking the carburetor and half of the bolting surface off of the block. I used a toilet paper to reform the intake hole and painters tape to make a form then poured JB weld in to "recast" the block then filed it down and tapped the mounting hole. That lasted 7 years. I must say that $5.00 worth of JB Weld paid off time and time again.
Thank you!
I used JB to weld a broken / cracked exhaust manifold on my crownline boat! It worked great. JB might not be perfect in all applications, but with good preparation you might be surprised! I have even bonded and then machined parts. It’s great stuff!
JB is a great product!
