RE: fuel proof spray paints?
I was trying to paint a cowl a few years ago, and tried all the over the counter spray paints. Nothing worked. All started to peel and soften within a few days of flight. Finally I just painted it with the color I wanted. Once that paint had cured, I coated the entire thing with acetone thinned 30 minute epoxy. A little really went a long way. Applied the epoxy with a latex rubber glove and my finger. It gave the cowl a beautiful high gloss finish, the color hasn't faded, and paint hasn't softened or peeled in over three years.
