This all reminds me that I need to finish painting my Sea Duck...I actually won Model of the Month last month with it at my club's meeting, even though it was unpainted...
I've got a Duster I'm painting that's made out of DTF foam, non water-resistant, and I'm trying a different painting technique than the Minwax that everyone's been doing - I've hit it with Rustoleum 2X primer, and I'm going to follow up with Rustoleum White for plastic, then airbrush on a pumpkin orange striping to make it look like Dusty Crophopper. So far, the primer has not caused any lifting of paper from the foam, but if it holds up, I'll be using this to lay down the yellow, red, and light brown on my Sea Duck!
