I've had nothing but trouble with this crap. It's nearly impossible to airbrush without causing a pool of caustic paint to form on the plane, ruining the finish. I know you're supposed to paint at 15psi. The gray primer simply doesn't work as a base coat . Just now, I picked up my hasegawa 1/32 sabre to move ti and left five deep fingerprints in the finish !!!! AAAAARGH!!!!! The plane's been finished for two months. I HATE ALCLAD!!!!
