I haven't tried catalyzed clear, where you mix 2 parts and reducer to see if it is fuel proof. It might be, but its also expensive.
Heat curing is not necessary with automotive paints. The "secret" to auto enamel is to add a hardener. I have a 20 year old glow powered model, finished in automotive enamel, using a hardener, and the finish is still in great shape.
This hardener works well in Rustoleum, too.
Be aware that this stuff is hazardous, and proper protection must be taken when using this product.
The hardener is the "Wet Look" product, pictured below. It serves as a gloss enhancer, too. Te feature is especialkly evident, when using it in Rustoleum.
