Review: Amazing - Does what it says on the tin, had a small puncture hole in my sump, sealed it no leaks Review: Fit for purpose low cost sealing putty. Recommended - 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.

But if you are using it to repair, say a hole in an exhaust for example - the original jb weld is too thin and will also crack with vibration after a while. The high heat putty is great for filling a hole and moulding to how you want it and It is also easier to work with. It is flexible and wont crack and is especialy for continuous high temp too. **Q: Could this be used to stick a heating element in a microwave oven.** A: Definitely NOT! Tried in in a siimilar situation. DReadful fumes given off. **Q: Would it work to fix/glue a broken pan support for a gas hob?** A: I wouldn't think so, as it is poxy resin I don't think it would stand the constant heat from a gas flame. If repair is simply for esthetics and not use then it's worth a try. Good luck. **Q: can this be used to patch a small leak under a petrol tank on a classic motorcycle..?** A: Hello - no its bot suitable for that purpose, you need a specialised product for that job ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing *by M***K on 31 July 2026* Does what it says on the tin, had a small puncture hole in my sump, sealed it no leaks ### ⭐⭐⭐⭐⭐ Fit for purpose low cost sealing putty.

Long term review. *by R***E on 15 December 2024* 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.
