Thanks everyone for the suggestions.
Curtis and Mike, especially for recommending Metalizer Brass. I had just become aware they make a Brass paint and Mike's photo really shows this looks like just what I'm after ... the color and smoothness look perfect.
Ismael .. interesting take with using a dark color. I've mixed silver and gold, but never occurred to me of using something dark. Now I'm wondering what that might do to metalizer.. I don't even know what solvent base that is.
I'm not sure I've tried regular old Testors Brass, Harry ... guess I figured Model Master would be their better Brass paint, but I'm really disappointed in it.
