For my glo planes i use Rustoleum rattle can paint, after paint cures i use Spraymax K-2 clearcoat in a rattle can. This stuff is fantastic and fuel proof to my 15% fuel.
My 1960 Orion still has the original Stit's fabric on it. I stripped old Sig paint,primed and repainted with Rustoleum and top coated with 3 coats of the Spraymax K2
Two years of Florida sun and Morgans fuel and it still looks like i finished it yesterday.
