Rustoleum paints are fuel proof available at Home-Cheapo and Wally World. There are a few Olive Drab colors available too.
I have found a few select colors of Rustoleum that seem to be resistant to nitro fuels up to about 15% but not all of them by any stretch. Particularly the metallic colors are definitely not! (Ask me how I know.)
