Automotive urethanes and clears will resist well , but color overcoated with five minute epoxy will remain clear and holds up to any of the fuels we commonly use if spills are removed for me anyhow. I put it over most enamel basses and you have a very clear fuel proof overcoat over a good resistive finish to start with.
Have also mixed the enamel into the epoxy successfully for a single coat application for a clearless flatter appearance. ( Like black or silver for fuelproof firewalls)
Krylon fusion will mix and dry normally. Small quantities, local availability lots of colors.
Far less expensive than the auto urethanes and necessary reducers and quantity purchases, just to go bad in the can in a month....
Bread crumbs. Lol
