J-B Weld HighHeat

This stuff is great! I just used it to patch a cracked exhaust on our Toyota Corolla. I was about to invest 300 and parts plus an hour or two in labor. But when I inspected the exhaust closely from the Cadillac converter all the way back to the muffler. I noticed almost everything was in pretty good shape other than the one spot where there was a hairline fracture. Right after the joint, headed towards the muffler. On a whim, I decided to check on here to see what they had for muffler repair because I hadn’t been pleased with the local advanced auto had on the shelves. I found this and the JB weld muffler repair. I bought both, but I ended up going with this because I thought for my particular situation this would be the best. I’m glad I did. It was really easy to use. I prepped the area by wire brushing around the crack. And then using a rag with isopropyl alcohol to clean before applying. Wasn’t sure how much to use, but I put on a pair of latex gloves and cut approximately half the product to use. I mixed it with my hands while wearing the gloves until it was a uniform color and then I applied it to the crack all the way around the muffler. It was easy to apply and mold into the shape I wanted. It was only like 40° outside, so I propped up a heat gun from a distance and let that hit it for about an hour. After that, I didn’t start the car until the next morning but when I did, it sounded perfect again! So far I’m really happy. I haven’t driven the car much yet so I will keep the review updated. But so far I’m very pleased and hopeful based on other reviews. In my case, I would rate this an incredible value for the money!

I have this on-hand in case my old beater muffler gets a hole in it. It cures quick. I haven't used this batch yet but I know it works already. I've used JB Weld before. It's tough. This one is high temp and good for many uses. It's easy to use, just knead the two parts together and use it like putty. Clean the surface well and if suitable, sand the area lightly and you will get good adhesion. Make sure you clean the area with some brake cleaner or something like that to remove all oils. If you keep adhesives refrigerated you can extend the storage life dramatically

Very good quality, works as described, it sticks very good

Works well...but...not under pressure !!!

best product on the market

Radiator intake broke off. I reattached it with this product. Like new and holds up to high temperature.

Lasted for 3 months only

When a part is too expensive to fix, bust out with the JB Weld and slap that bad boy back together.

Good product. Good price Used it to plug holes in a classic car radiator as a cheap, temporary fix for testing a project. Easy to use. Took me a while to figure out the material was wrapped not in a cellophane tube. Once I’d figured that out it was easy to cut lengths off without disturbing the remainder. Worked well. Hardening time is longer than 8 hours in the UK. Leave overnight would be my advice. Pressure tight. Recommended

Tres efficace, facilite d utilisation

Product delivery than schedule but it look old and dusty.

i used this in my power steering pump and it stopped the leak, heat proof and durable. 100% recommended.
