I'm glassing and painting an airplane and have found the color I would like to paint on it. The paint is Duplicolor Aluminum which is an acrylic enamel. Because it is an automotive paint I assumed that it was gasoline proof. I primed and painted a piece of test scrap. The paint dried to the touch in about 20 minutes. I waited 24 hours and then tested to see if it was indeed fuel proof. First I dried 91% alcohol and the paint softed. Then I tried gasoline and the same thing happened.

Does anyone know what may have happened here? Could the paint need more than 24 hours to cure?

Thanks,
Jim

long ago when i was painting cars with acrylic enamel it took along time to cure and get hard we are talking months not houurs.laquer was moer popular as it dried in a few days.

I use Rustoleum Auto Primer and Paint. Make sure it says helps prevent rust. This stuff has been fuel proof for me after I let it dry a couple weeks! Menards sells it and it's cheap. Good Luck!

FYI, I just got this response from Duplicolor's tech support:

Jim,

Thank you for taking the time to contact us, we appreciate your interest in
our products. After the paint has cured out for 5 days, our enamels will
be able to withstand a splash or spattering situation where the gas is
wiped off right away. Unfortunately if the gas overflows & is allowed to
sit on the surface for a little while until cleaned off, it will act as a
paint remover, or at least discolor the surface. It would be best to go
to a body shop and have them coat the surface with a 2-part catalyzed clear
coat if you are worried about gas spills.. This application will provide
the best protection against gasoline on the surface.

Good luck with your project..

Regards,
Ray

I guess automotive paint is not fuel proof. Who'd a thunk it???
