I have used Rustoleum paint from a rattle can and have sprayed it from a spray gun,both were fuel proof.I use 25% and 35% nitro in rc boats and never have had pait lift or bubble off.You must let the paint dry,sometimes it takes 2 or 3 days to vapor off.I have painted plywood,put the plywood in a jar of 35% nitro fuel for 3 days,and not had the paint lift.I have used Red Devil Polyurethane
paint ,only for stripes and graphics,and have not had the paint lift,BUT,I have cleaned the boats after every run with Windex.I have painted 1 plane,a Bipe with Rustoleum paint and it has not lifted or peeled in 2 years,BUT I clean the plane after every flight.

For what its worth,Butchman
