J-B Weld 8297 HighHeat Temperature Resistant Epoxy Putty Stick, Machine Gray, 2oz

Does what it says on the tin, had a small puncture hole in my sump, sealed it no leaks

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

Had a small hole in our hall radiator. I was skeptical to tell the truth. Hallelujah, it actually worked. Sealed the hole, no problem. Over a year now since I did the repair. Still no leak. Once the putty sets, it goes rock hard. Handy stuff to have in the tool box. Highly recommended..

Amazing stuff worked much better than expected. Filled a 2cm hole in exhaust with no signs of it coning off any time soon.

Great stuff. Dries real quick. Highly recommend

I bought this after discovering a crack on a pipe, it was too difficult to replace it so I decided to give this epoxy putty for metal a go. I prepared the surface by cleaning it thoroughly and I used a metal file to scuff the surface and get mechanical adhesion. I mixed the putty thoroughly for a couple of minutes, and use a tiny amount for the crack, pushing it right in, then I used a bigger amount to create a full ring around the pipe to make sure the crack won't get any bigger since the pipe has no room for expansion. I left it cure for about 20 hours. I'm happy to report there's no leaks!

Failed to hold exhaust into the muffler. Held for 5 minutes before it came loose again

Good

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!

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.
