There are many, many threads here from guys who have tested the spray can polyurethane and other hardware store paints. I haven't seen one yet that said any of the rattle can poly was fuel proof.
I sprayed Minwax Polyurethane over Solartex, on a glow powered model. The model has flown for two seasons, with no degradation to the finish.
This is the polyurethane, not the waterborne polycrylic.
This paint was from a quart can, however, not a spray bomb.
