From what I know about Rustoleum is that it is relatively fuel proof up to about 15% nitro. Use the regular kind of Rustoleum enamel. The Camo colors, I believe won't be fuel proof. However, their is no reason why you still cannot use them. You just simply have to cover the plane with two coats of clear coat to cover the camo paint and keep it from breaking down. Some guys even paint their WWII planes with latex, then use clear to fuel proof. I have found that one of the best clear coats is two part automotive type. Most auto shops can premix it and put it in a spray can for you. Just tell them you what you want. I believe you can also get them in semi-gloss or even a satin finish if you like. Just remember you need to have a flex additive added to the clear coat so it won't crack, and once it is mixed with hardener it will harden even when they put it into a can, so it needs to be used within a couple days.
