Generally speaking, the acrylic auto paints are fuelproof. as are most of the polyurethanes.

Whatever paint you use, fuelproof or not, all it takes is a fuelproof clear coat to make it work fine.

you want to stay with the airraft lacquers on fabric because of the flexibility. A lot of the various enamels will check or crack.

You can do a quick test for fuelproof, bearing in mind that many become more fuelproof as they age. Many of the ordinary Krylon sprays are fine after they age a week, but the day after you shoot them you can wipe the paint off with fuel as a solvent.

It comes down to shooting test panels, test them as they age.

Or just clearcoat the whole thing and don't worry about it.
