Can JB Weld be used to fix automotive rust holes? Could it be used to glue on patch panels? If you don't have a MIG welder, I believe it could be a viable option for rust repair. What do you think? / @lakesideautobody
@@LakesideAutobody Seemed okay. It was a few dime and quarter sized holes by the rear lights on an old Dakota. I actually used the JB Weld metal putty - the 2 part you mix in your hand. I applied it from behind and over the hole and squeezed the two globs together. They hardened up, I sanded, primed and hit it with a spray bomb. I wasn't looking for a professional job, just to get rid of the holes. I WOULD be interested in seeing if the regular JB functions the same as a panel adhesive (seems much less expensive to me).
As a side hobby, I have been using JB weld to patch rust holes as you have done. Gone back to check on those affected areas many years later and repair has held up very well. Will be doing again soon for some rust spots on the roof of my 28 year old truck.
That is great to hear - the hole that I patched with the JB is still in good shape too. I think it works well because it seals the patch real well like panel adhesive. Thanks for your input - have a good weekend :)
I used JB Weld once to patch a hole in a gas tank, was actually a crack a little more than an inch. First dried the tank. Drilled a small hole at either end of crack to prevent further cracking. Sanded lightly and applied generous amount of JB Was lasting years later when I sold the car. Great stuff.
@@100M2B When I said "wet" , I do not mean soaking wet . Let it set up ,then if you see any unevenness or small flaw use the alcohol .Put a small amount of alcohol in a cup , then just dip your finger in it and then smooth it off useing your bare finger . Then clean your finger b-4 picking nose !
Not body work, but used JB weld 45 years ago to replace a 2"x1" hole in the side of a briggs mini bike engine, my grand kids still ride it today. It's as good as it gets for non heat repair. Enjoy your videos very much. Thanks for taking the time to share them with us.
Repaired a hole in the side of the case on an 8 horsepower Tecumseh snowblower engine. Previous owner had run it out of oil and it snapped the rod and put it through the side of the case. Cleaned up the pieces of the case and repaired from inside and outside with J-B Weld. After a new connecting rod and some muriatic acid to clean the gold aluminum off the crank journal, the engine runs great years later
I've used J B Weld, other epoxy adhesives and polyurethane construction adhesives for various auto body work. Adhesives join the components together and seal them from moisture and corrosion. Low stress panels don't always need to be welded. You'd be surprised how many body components on new vehicles are bonded with adhesives, rather than being welded.
@@deadprivacy Why patch with any product metal is cheaper and welding is better more drain holes and internal rust treatment obviously that is a good look patch job not for my restos 🤔🤔🤔💯
@@jackbarrie6007 I don't have a welding machine. I'd buy one but my single condo garage has no extra room. I have 4 cars and some motor bikes and am just out of space. If I had a 4 car garage I'd have a proper repair shop with a lift in it. But I just don't. In my town, that would be a $2 million house. I have a truck with rust holes in the cab floor from a leak from my loose windshield. I'd love to put in a proper welded patch but just don't have the proper tools. It's between something like JB Weld and taking it to a body guy and paying fair but still very high price to have it done right. Probably $300-400 vs $10. The floor is still sound so I'm thinking that JB Weld would do the job. We all know that perfect is better but perfect just isn't possible sometimes. I have lots of toys that need things and one has to set priorities.
Fibreglass and metal do not bond together,they will most definitely separate,as a body man,I have repaired so so much where people have tried using fibreglass,WILL NOT work,just trying to save you from future problems
Well done. I pondered the JB Weld idea several times, but never gave it a try. After seeing your work, I'm going to patch a couple of areas on my old truck. Thank you for sharing!
This is the best thing I have ever come across in my years of doing body work. When used acetylene and oxygen the metal bends like it's a wave. I use the six minutes setting time because the curvature on the panel. So easy to work with the stuff. Thank you I wish I could send you a picture.
This video gave me so many ideas, thank you so much. I have a project that needs repair and I'm no welder, no do I have the pocket deep enough to take this car to an autobody shop for repairs, your videos are a blessing to us. Thank you for all you do and sharing with us.
I use JB Weld for many things. If prepped and cleaned good, it sticks to aluminum very good. It can even be tapped if used in not too stressful projects.
I have used that method on a windshield opening that had pinholes in it. Worked great. It was too delicate to weld patches and it really made a smooth repair that should last a while
Back in the early 70’s a guy brought me a motorcycle race bike where its piston was fractured. A piece of the piston skirt became lodged between the crank and the lower case fracturing the case. So I went and J B Welded the case, bored out the cylinder so I could put a new piston in it, and then filed down the case halves, tapped out the locations where the case fastener bolts once were and the guy raced the bike that weekend. It was a lot of work but, I couldn’t get a new case for at least two weeks so… if you’ve ever watched the movie “On Any Sunday” with Steve McQueen… you know us hard core motorcycle racers of that era were back on the track every weekend no matter what came our way that tried to stop us 🤪 in other words; we were a bit nuts, if you will. I’m going on 76 years old and still doing things things with J B Weld that might shock some people. Not the quick or fast cure version… just the long cure type. I haven’t had the same success with the fast cure. Back to the J B Weld fix… to the best of my knowledge, it worked fine. Well… I never saw him again ? Every time I mix a batch… I think of that early 70’s motorcycle repair, lol…
Used JB Weld to rebuild rusted lower windshield pinchweld area. Front windshield rubber dryed and failed over time allowing water to reach pinchweld and cause rust. 1966 Chevy C10. Replaced windshield and gasket and molded JB weld in contour of pinchweld so rubber gasket sealed. Beauty. .... Plan on trying to use it to repair and build up rusted portion of wiper motor mount hole also.
This is a great idea. I welded on a new floor to my 60's Vespa and still had a few very small pinholes that rather than filling them over with epoxy primer and then filler I'll simply use a bit of JB weld first.
Love your videos. I had saved many of your lessons and had to find you again . I wanted to thank you for all I learned from you over the years, I’m improving as a DYI HOME GUY BUT HAVE GOTTEN EXCELLENT RESULTS.
I too have used KB Weld for small holes. Also used it on an S-10 pickup throw out bearing one time. Was still in there working just fine 150,000 miles later when I sold the truck. Good stuff!
I've been using this same method to fill holes in my 02 Silverado bed & body for a couple years now. I don't bother sanding or painting them since it's a just truck for hunting, fishing, hauling excess yard waste, bricks, etc. I step on the repairs, throw logs and bricks on em, holds up just fine. It is also is a better option for we who have pacemakers and shouldn't be around welding.
Thank you for posting this. Have used JB Weld over the years for other applications and have held up well. Restoring a 63 Impala and have several small areas to repair inside the rear wheel well area that welding isn't an option due to the location to outer quarter panel risking paint damage from too much heat. I will use this option there. Thanks again for posting...always learn from your videos.
Glad to hear it AC - This video shows how long this really lasts. The drivers side cab corner was glued on w/ JB Weld - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gIS1Tbv7Kvw.html JB Weld Repair vid - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wRl1QfkrBeY.html
I agree that JB Weld is probably the best repair substance that I have ever use. Second to none. The only problem that I would have with repairing rust on automobile's could get really costly. JB Weld is not cheap. Bondo type materials are much less costly per square inch of surface's. Maybe JB Weld will see your video and create something that is less expensive to compete with Bondo.
I used JB on a few pin holes I noticed after I put the epoxy primer. On the bottom of the front fenders I cut it out and welded in a piece of metal like you do. To many holes on the bottoms. Thanks for all your help. I tell all my friends about your videos. Practical body repair.
Not at all. For those in the know JB Weld is easily a replacement for kitty hair (reinforced body filler). It is super cheap, just as flexible, just as sturdy, and sticks to pretty much everything.
Nice Video! I agree that JB Weld is a good option for rust repair. I have used it as well as Loctite PL Premium 3X contruction adhesive. No hardener needed. Dries like a rock! Cures in a few hours, but best to leave it overnight. It's sandable but you need some elbow grease to do it. Good to make a foundation using the 3X and some metal. Then use bondo over it.
JB weld is definately a viable option all day long ,just look at the fantastic repair even with just the primer and its like nothing ever happened ?brilliant and its how i have been repairing rust holes for years now brilliant job mate you are truly inspiring blessed .
I appreciate the support Joslyn - It can certainly be an option. Make sure the panel can drain and stay dry - squirt some oil in there like this - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8XaZBy7GC7A.html and you'll be fine. Have a good week my friend ✌
I've seen people fix toilets, house doors and fenders with ramen noodle and superglue. This seems like a solid idea to me. Especially on an older vehicle that is still very usable but not worth a body shop price
I used to repair and rebond my front fender on my 1976 modded c3 vette . Having owned the car for 40 years the front fender must have been in accident and the door gap was way off and bugged me so as I prepping the car for my home brew old school blue and diamond metal flake custom paint job . I cut the fender and rebonded it and added glass and smc comparable resin ( be carefull as many of the panels areSMC not fibreglass and could be un bonded if you standard resin same with filler must be SMC comparable for 1971 and newer c3 vettes . Any way I stuck the fender back in place with industrial grade Jbl not the 10min stuff the industry takes 48 hours to fully cure and comes in big tubes don’t use any Quick set epoxy it not as strong . Epoxy work great 1 if you do the prep correctly . If your lazy and use over rust paint and dirt and un sanded material don’t bad mouth the inept results lolol
JB weld and fiber glassing make great temporary / affordable patches and do help to preserve the remaining sheet metal. However, Tig / Mig welds might be a better repair option since jb weld and other epoxies have different expansion and shrinkage ratios than the surrounding metal and /or the patch in heat / sun or extreme cold. Over time this could cause pitting/bubbling, high / low spots, unevenness, or imperfections/warpage in the finish/paint. Depending on the condition, make / model, and value of the vehicle full metal repairs might be a better option.
Great job and I've got to say I'm impressed by the comments as well. I thought there'd be 500 people telling you how you did it wrong lol. Have you ever tried any of those rust converters on pitted metal? It supposedly seals it and keeps the rust from spreading. Of course after you clean off any of the loose material.
My boss used to make us use that - turned the rust black or into something else. Never knew of any come backs so I think it worked pretty well. I'm surprised as well about the comments - thought they'd really give me the business.
Be sure to get a good brand. Used one from a local car-oriented chain and it was horrible. Sometimes it turned rust black and sometimes it didn't work at all. I am currently using Corroseal which seams to work well. Just not sure if there are any issues with applying body filler over it since I don't believe the rust converter should be sanded post-application.
@@Marcoosianism I always use corraseal before I patch. It's the best chance of killing that rust before you close up that area. I use fiberglass poly like duraglass over it so water won't swell it up like regular bondo. And only use bondo and glazing filler over that. The secret is to seal the inside so it doesn't come back through. I also spray bed liner on the inside or backside of patch. It's buttoned up and solid and most important waterproof. It'll last years.
Great job I just picked up Jb weld steel stick to patch the holes in my rear door I removed the impact strips I’m going for a real clean look,but after watching your video you have me an idea about using sheet metal to cover the hole
I was thinking that it would be good to squeeze in more JB weld to fill the narrow space between the inner and outer sheet metal. To reduce the amount of water that can be trapped in that space. Also it seems to me that welding always has a disadvantage in that it cooks off the factory protective coating on the inner surface of the metal and you can't recoat it once the repair plate is in place.
Sad thing is, there is no protective coating in the pinch welds from the factory. Some companies use weld through primer and others treat the panel after the welding process leaving two pieces or three pieces pinched together and welded with nothing to protect - thus the rust at the edge of panels usually. Best way to protect is after the repair. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8XaZBy7GC7A.html or ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-y05dNxt-nVc.html
OMG you just saved me a ton of money....I have a 97 Aerostar and am trying to save it from the junkyard. Quite a few mini rust holes and this would do the trick. Thank you!!!
Works great, I used JB weld to secure strips of sheetmetal to fix holes in the roof line and windshield surface. its been 18 months of WI weather and its holding up just fine.Al
Hi use J-B Weld to but I put the fiberglass cut out sheet that's woven next to it and I spread the J-B Weld over my fiberglass on both sides and that's how I get some big big patch panels with fiberglass cloth and it works incredibly well also
Im just learning body work myself.. ive recently discovered jb weld is a fantastic filler for rust holes. The only advice id give here... it bothered me when you sanded the jb weld and went right to bondo. No dust clean up done? Was it edited out? Also you spred the bondo well past the repair area up past the body line.. it was cringe worthy. (For me) and a 3rd note... instead of using heavy filler to go over the jb weld.. just use more jb weld. It sands beautifully. If its left with a tiny air bubble or to use more jb! Body filler is antiquated. Jb doesnt wear or shrink or crack. There actually teaching to use jb in autobody classes now.
Body filler is easier to sand than JB + way cheaper, thus the coating of Bondo. Can't be afraid to spread the filler larger than you need - aids in getting the repair straight. Finally, you're right it is a good idea to blow the dust away before the next coat of anything - filler, primer, etc. Happy Holidays
Are they selling jb weld in something larger then little tubes to bring the cost down? Otherwise people will stick with the body filler to cut expenses
@@justafanmarvel9669 It is expensive - might want to explore the use of panel adhesive (also expensive) - I once glued the whole floor of a van in with metal roof cement/caulk 'cause I didn't want to mess up the galvanized coating by welding it in. I glued and screwed it. It never moved again - that'll be the last thing left on that van 50 years from now :)
I personally don't have the skills to weld sheet metal nor the tools so if I was trying this kind of job at home, it'd be easier to use a putty based substance like JB Weld. However I can imagine that if the rust damage was more extensive - it wouldn't be as easy and would likely require a professional to weld it.
@@sdaafasfad for that type of rust, welding isn’t really an option. You’d have to cut down to viable metal first rather than just grinding away the rust.
I got this idea today and wanted to see if it has been done. Glad I found your video with excellent demonstration. I was welding in a patch panel and burned a few holes and was thinking, I hate the thought of trying to weld up those holes and know there is enough good weld to hold it all together. I know ordinary body filler wont cut it because it is not water proof, and thought maybe jb weld. Now will try it for sure.
Here's a cab corner repair that's 4 years old now - still fine - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wRl1QfkrBeY.html - follow up 3 years later - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gIS1Tbv7Kvw.html
The water inlet seperated from my radiator and started leaking pretty badly. I cleaned up the area and JB welded it and it held for the duration I owned the car.
I've been using JB Weld for filling trim and emblem holes for many years. If possable use the epoxy to glue some metal screen to the back side of the panel. When that dries use the epoxy to fill the hole and push it through the screen. The screen helps keep everything in place.
Love the real info on here saves dollars old school real awesome listening to the well done videos will save you money 💰 and time . Don’t forget to oil the repairs from behind better yet oil spray the entire car it works it works great if applied yearly and covering everything inside all boxes hidden sections also drill 1/2 holes 100 plastic undercoating plugs $6.99 in Canada
Well I think this is freakin stupendous! I'm going to try to apply this method to my f150 chassis. Using much more apoxy whether JBWeld or Numetal. Clean the area, cut out a piece of metal and apply. It should strengthen the chassis. Thank you!
