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

Seems to be a fantastic product! I bought this after my car developed quite a serious coolant leak from a metal pipe part of the engine. Wanted to use it as emergency fix really, however it turned out so good that it has become permanent fix until I have the will and time to take the car to the garage. I have filled the instructions to the letter and left it dry for 12 hours, just in case... I waited with this review for nearly two weeks to see the actual performance of the product... It hardened to a rock hard substrate and sealed the hole completely and reliably. Absolute bargain as well! I've put some before and after pictures. Can't recommend this enough!

Very easy to use, fixed hole in washing machine drum. Would definitely recommend

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..

This is great stuff, does exactly what it described it would, metal to metal at high heat. Great stuff

Surprisingly good!

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

I found this very easy to use due ro easy instructions, as you only the amount required for use to be applied. Like the instructions say you have to knead the putty like working dough between your hands so that the outer darker area of is mixed with the inner lighter part of the putty to activate it before applyito to the surface area, but you must prepare the surface to with some sandpaper and clean it to make sure the putty has good surface to work with in the end. Once done it states it takes 8hrs for it to completely cure meaning you can even drill or sand it afterwards, if need be. I did find the i was able to shape it to plug the hole in pipe while while smearing it around the pipe, as to make sure it worked like a bandage to prevent tye potential of exhaust’s gas pressure being able to blow it anytime in the future. I wore rubber gloves while applying the putty with my hands which made it a lot easier to work seeing it can dry within 2hrs which means you can tell its just starting to thicken a little while still being mailable to continue shaping to surface area meantime. Remember, its up to 2hrs to drying but 8hrs to completely cure before being able to drill or sand it.

Good

ho usato lo stucco per saldare la filettatura al tappo scarico olio dello scooter si era completamente crepata. Regge da due mesi senza alcuna perdita...va impastato bene e applicato in pressione lasciandolo polimerizzare per almeno 12 h meglio 24

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
