i've painted a lot of things in this mans hobby, but i never had the oportunity to paint a metal fuel tank until now.
i've always had tanks inside--outside--brass--plastic, but now I want to paint it to match the plane. I have to use the same color dope on the tank! My question is, what type of prep do i do, to get the surface to accept dope, and not come off after 10 or 20 flights?
keep sanding
