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

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

⭐⭐⭐⭐⭐ *Excellent high-temperature epoxy putty! Easy to knead and apply, and it sets into a very strong, heat-resistant bond. Perfect for exhausts, engines, and other metal repairs. Once cured, it holds up really well under tough conditions.*

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.

Good stuff does exactly whats decribed on the packaging.

Not good. I use it to fill up a hole on my car exhaust but doesn’t hold.

Seals holes in exhaust parts perfectly. File grind or drill when set. Easy to handle two part putty the mixes together to start harding but in a controlled way

Great

Tres efficace, facilite d utilisation

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.

للاسف كان به تسريب مايشبة زيت المحرك اعتقد انه بسبب سوء تخزين

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