Why should I pick this product when the J-B Weld Original Epoxy Adhesive has a higher temperature limit at half the price?

The original jb weld is great for bonding things together and at high temps too! 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.

Could this be used to stick a heating element in a microwave oven.

Definitely NOT! Tried in in a siimilar situation. DReadful fumes given off.

Would it work to fix/glue a broken pan support for a gas hob?

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.

can this be used to patch a small leak under a petrol tank on a classic motorcycle..?

Hello - no its bot suitable for that purpose, you need a specialised product for that job
