Thanks all for the help. I'll try Rustoleum and do a test area with raw fuel and with the engine running for 12 min. time and wipe the area to see if the paint stays.

Before spraying the coke bottle cowl, should I sand the the area to be painted with 200-300 grit sand paper to roughen the area for the paint to adhere better ?

Thanks for all the great advice
