I've no direct knowledge of auto-paint techniques... however I've taken a good half dozen or more plastic Heli canopies to an automotive shop who did the painting and work for me.

I know they applied some sort of hardener.

The results have been fantastic.

At first I was afraid that the automotive paint would crack given that it is painted on plastic.

This has never happened.

Glow fuel seems to make no dent in it as well.

I've used Krylon with a primer base on cowls I've repaired or rebuilt, and glow fuel and gasoline seems to have almost no effect on it.
