Hello there L-46man,

I would imagine it would have to be with that "particular" epoxy mixture because there are so many types and chemistries of epoxy adhesives. I would be hesitant to say it works on all epoxies as epoxies are used all kinds of high temperature applications. I used Epoxy to fix an old two stroke outboard's cylinder head crack near exhaust and it has dozens of hours of runtime. It is been exposed to high heat but nothing like a torch. It also might make a difference if it was bonded properly as they were not intended to be removed.

Bought a Kit to "Weld" Plastic, very handy tool from Eastwood. 90% of the process is learning to being able to tell which type of plastic it "is" as there are you can fix it. One material will stick to one but not the other. They show you how to test all the most common types so you are sure to use the right method or it just won't stick.

The items in the pictures from Spoticus are amazing, I wonder how that particular stuff ever got into a lubrication system that is filtered. I have seen RTV chunks blocking the intake screens and it was the result of a guy trying to save a few bucks by changing his Head Gasket on one side. Cleanliness was not his strength and his motor lost oil pressure due to the blockages from all the loose pieces of RTV and gasket material seemed to make it to the oil pan.
