RE: Rustoleum Gloss Clear
Someone will tell you to test it by spraying a test piece and pouring 15% nitro fuel on it. You can only be sure if you test with the exhaust from a engine. Make a test piece, and next time you go flying, put the piece behind the exhaust, while your engine is running, set it in the sun and at days end, take it home with you and see if it softens. I think that is the only way. Then let us know. If we all did it this way and posted the results, we would not have to waste a can of whatever to find out.
