hello there. Brand new to air brushes, but have some experience with hvlp, spray cans, etc... I mainly work with sheet metal as a medium, for signs, auto, tool boxes, etc... I’d Like to find out suggestions or insight into what kind of paint is compatible with Auto Air Color from Createx. I ordered a set of transparent and opaque from them. I’m working on pieces that are up to 3’x4’, so I don’t think I want to do the base with the air brush, nor with paint that runs $8 for 4 ounces. Is the a clear primer for metal or can I use clear top count as the base to allow the metal shine or grinder texture come through? And then airbrush over that and then finish with the clear? Also curious about opaque base coats. Can I use rustoleum, krylon, Montana, Duplicolor spray paints as a base safely? Interested in their normal colors as well as some of the specialty paints like their candy paints.
