I use flat paints, only, with a clear glosscoat finish.
From my 1/35 scale armor origins, I just dont trust the gloss.
Moving to airbrush as the main system, but used a spray for my Al Bundy green '76 Gremlin.
Satin green as the car I was modeling.....and despite numerous tests, it failed me big time. Looked like heavyilly textured paint! Awful!
Impossible to repair, so I have no choice but to turn it into a rust bucket. The car in the show had a pretty finish. Guess I'll have to acquire another body, or chock it up as the REAL Bundy Gremlin (never made sense in the show why a show room Gremlin wouldnt run at all)
Anyway, my first spray paint disaster in 50 years, so I guess I shouldnt complain.
