RE: Fuel proofing help!
I paint with acrylic all the time. Once the acrylic is fully dry, I coat it with 6 light coats of TopFlite Lustkote clear then let it dry for about a week. My Hanger 9 Fokker DVII has acrylic painted parts and it is over 3 years old. The plane has had many flights on it and it is still fuel proof to this day. [8D]
