RE: need a correct answer about fuel proof paint.
LusterKote is also fuel proof. It is an acrylic lacquer, so test what you are clearcoating for compatability. I have applied it over Rustoleum (well -cured) without problems, you have to mist on several light coats. The LusterKote clear is available in gloss and flat.
A guy in our club is a wood finishings expert, works in the furniture industry. He is adamant that water-base polyurethane is NOT fuel proof. Even oil-base does not stand up to a constant exhaust stream of glow fuel. He repainted the landing gear winglet on his DR-1 several times while flying it with glow engine, finally got tired of it and put in a gas engine
