Hi cbaltrin, You stated you have airbrushed MM metalizers over bare plastic. My project is a 1/48 scale Falcon 10 business jet. It will be over all gloss white(enamel). The leading edge slats are polished aluminum. Ques: Should I mask off the slats(bare plastic) first,and then prime and paint the white wing surfaces? Then mask off the painted surface and spray the slats with metalizer? (I'll be using MM Aluminum plate "Buffing" metalizer,with an airbrush). Any recommendations or suggestions is GREATLY appreciated.......THANKS! JohnZ
