The Best Way To Use JB Weld

[@ahassen1236]

That Cockerel in the background must disturb from your JB Marine Weld dream each morning! 😂

Good tutorial! I bought the marine weld based off your review: evidently you have to be careful because there are even different types of this specific formula. I got the one in the syringe for convenience/consistency, but it cures quicker and is far weaker. Frustrated I wasted money on it, but I might give the "twin tubes" a shot.

Thank you for this video! I'm glad that I lost the instruction for my marine weld and found your video because I think the steps of sanding and alcohol are important.

Great video, This marine JB weld looks great I'm want to cover 13 antenna holes in a ex police car so I gess this should work great holding the metal patches on than useing the JB like bondo to cover it up than sand and paint over it .

Thank you so much for making this!

Thanks for making this video. I had been trying to figure out a way to repair my aluminum grass catcher.

[@nhojcam]

so, quick question.... what about heat cycling like with an aluminum transmission case. how well will it hold up? what i want to do is basically the same lamination application exactly as you've shown. i want to add an aluminum 1"x1" square to the bottom of a transmission case as a boss to increase thickness of the case in order to be able to drill and tap to install a transmission oil drain plug. the case is too thin by itself to hold a tapped thread, so i need to increase the thickness of where i'm going to install the self-tapping drain plug.

thank you!

Does marineweld setup Rock hard or does it have a bit of flexibility? I'm told it setups fairly hard but you can still dig a fingernail into ....somewhat like a very dense marine silicone etc.

[@mr.upcycle9589]

It seems like it's slightly flexible. I fixed a leaky cast aluminum hot water port on a vehicle and it lasted a very long time.

i have a leaking abs traction control unit that isn't built anymore for my classic BMW i want to do this to plug the leak. the clean and scuff i can do but it is a slight leak of bake fluid so i can not get it completely oil free will this work still

[@mr.upcycle9589]

Probably not, the mating surface has to be completely oil free. If there is not alot of pressure could drill it out and use a rubber plug or something.

[@texansnstros]

If you need to build it up, to you just put it on thick or do multiple applications. I am repairing a spot where my boat trailer put two small holes in the front of the boat (above the waterline) where the roller came off.

[@bradschulz377]

I'm wondering the same thing. I think I should have used marine type because i'm repairing a leak in a cast iron radiator; sort of a hairline crack. I covered it but the water is finding a way out. Can I put on another layer or do I have to start over removing the old patch?

[@mr.upcycle9589]

I would bet one large application. But if you couldn't do it in one definitely sand and alcohol in between coats.

Thanks for this video. Have been using other types of J-B Weld for many decades, but was not aware that J-B Marine Weld even existed. This is great news. Thanks again. P.S. Try using 99% isopropyl alcohol for surface cleaning before applying J-B Marine Weld - eliminates the possibility of residual moisture on the surfaces to be bonded. I buy small bottles by the case from Amazon - cuts the overall lost and limits contamination from using a larger container.

[@brycer985]

What is the difference between JP MARINE WELD vs JP WATERWELD? I am trying to fix a leaking dishwasher where the polypropelene got melted by a warped heating element and wondered if one had better heat resistance than the other. Also i think Marine Weld will handle the dishwashing chemicals much better.

[@cantuchtis]

Waterweld is a puddy. You cut it mix it and then apply it
