Finally I sprayed the gold. I had to buy enamel paint for the gold in order to get a match for a few bucks. I didn't want to buy $100 worth just for a thin strip. Worked fine.
Oh, the red is a metal flake and came out fine. Interesting car paint makes single stage in metal flakes. Airplane paint doesn't. You have to go base coat/clear coat in order to get metal flakes in airplane paint.
