Hi folks. I'm no stranger to painting and decaling models, but I have never done a brass piece before. I have a gorgeous NYC H-10a that I want to paint and decal, but I am lost as to what sort of paint to use, or how to apply it. My questions in particular are: 1) I have read that to clean the brass, you wash it good in soapy water and then lightly pickle it in a bath of vinegar for 15-20 minutes. Is this correct? 2) I have also read that I can use any sort of cheap auto primer; is that true? I usually use Vallejo grey acrylic/polyeurathane primer. Will this work, or does it need to be an "etching" type of primer? 3) I can easily remove the body shell and pilot, as well as the tender shell, for cleaning and spraying. But what about the frame, tender trucks, and so on? Is it best to simply paint these with a small brush? Or should I disassemble all the valve gear and wheels and so on? I hate to do this. And 4) can i use an acrylic paint, or is it best to use enamel? I could brushpaint enamels even and have them come out quite nice; I have never used enamel through my airbrush. In short... what do?
