J-B Weld is proudly made in the USA Review: Hardened Like Steel, So Work Fast - This stuff really does harden like steel, and it does it pretty quickly, so have a plan and move fast once you start working with it. My exhaust flange had completely rusted out and split in half, so I bought an exhaust flange repair bracket and packed this putty all around the repair, including on the threads of the bracket. Once it hardened, that was it. Ain't no way this thing is coming off now. 😅 It was easy to work with, stayed where I put it, and gets seriously hard once cured. Just don't take your sweet time getting everything into position because it starts hardening pretty fast. For a rusty exhaust repair where I wanted everything locked together and sealed up, it worked exactly how I hoped. Review: Repaired my exhaust with this! Saved me $$$ - 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! ## Features - J-B WELD HIGHHEAT: A hand mixable two part epoxy putty stick that is formulated to repair and rebuild materials that will be exposed to high temperatures in automotive and industrial maintenance applications.

(would work ? instead of having to replace the seal?)** A: I guess it depends on if you ever want to fix it right. Once you use this stuff thats how it will be forever, it's not pliable or removable **Q: I striped out an oil drain plug on a generator motor. But there is a second drain on the other side of the engine. Will this seal in oily environment?** A: if you are thinking about plugging the hole, yes, but if you have access to the inside of the pan i would use it to attach a plate to the inside. you could also grind down the outside free of rust / dirt and use it to bond a plate to the outside. i would be concerned about just using it as a plug, where using it to bond something to the pan would not span a 1/2 to 5/8 in. gap. you might even use a quarter or a nickle or something stainless that will not rust. after it sets, hit it with some high temp paint. **Q: Can you use this on ceramic pottery or is it just for metal?** A: You can,but for ceramic you dont need the high heat one, just the regular temperature version. This one is for exhausts etc.. **Q: Will work to repain a hole in car oil pan under the engine?** A: Probably. Make sure it is really clean, sand the area where the epoxy goes. Maybe plug the hole with a broken off toothpick if it is still on the car to keep oil from seeping into the epoxy. Put a glob the size of a quarter and make sure the toothpick is covered. Put duct tape over the epoxy until hard. Should work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hardened Like Steel, So Work Fast *by C***E on September 7, 2026* This stuff really does harden like steel, and it does it pretty quickly, so have a plan and move fast once you start working with it.

Most poor reviews are probably due to a lack of surface preparation. I used a wire wheel on a drill to prep surface to bare metal, cleaned with alcohol, mixed product thoroughly and had no problems. Several months later repair holding up fine. ## Frequently Bought Together - J-B Weld 8297 HighHeat 500 Degree Epoxy Putty Stick - 2 oz. , Grey - J-B Weld 37901 ExtremeHeat High Temperature Resistant Metallic Paste - 3 oz - J-B Weld 8267 SteelStik Steel Reinforced Epoxy Putty Stick - 2 oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/82260002-highheat-550-degree-epoxy-putty-stick](https://www.desertcart.tw/products/82260002-highheat-550-degree-epoxy-putty-stick) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-27*
