I just tested rustoleum clear (both gloss and satin). I let it set about a week before putting raw glow fuel on it. It was over rustoleum white on Worldtex covering. I used 5% nitro fuel. Both gloss and satin were affected by the fuel. The fuel made the satin shine more. The gloss changed a little also. The clear did not gum up or anything. I don't know what would happen if repeated several times as when flying. I decided to just paint the worldtex covering with rustoleum white and the trim colors without using a clear coat.
