RE: fuel proof paint
IMO Luster Cote is a pretty poor paint. Easy to get on too thick and takes forever to dry. Hard to get a good gloss also. Also not truely fuel proof. It will soften if wet fuel sits on it. I had a cheap pre spad kinda spad like plane with foam wings and just a piece of plywood for a fuse, the tank is strapped to the plywood right behind the engine. Only I used velcro stuck to the tank and fuse. Well recently the fuel line came off and fuel poured all over the front of the fuse. When I tried to take the tank off the Luster Cote stripped right off. It was soft but did not bubble up. IMO acrylic lacquer is the best simi fuel proof paint, followed by dope. The dope takes longer to dry but it still dries much faster than Luster Cote.
