Frank, I place my items on a a lazy Susan type thing and as @tomsteve does, get down low and spray light dusting coats from the 4 compass points, Cut back the surface with 220 or 360 paper and repeat, this prevents any build up on the edges. Sometimes I will turn the piece over and do the same from the rear. When I'm happy with the coverage, using acrylic paints, I repeat the process with lacquer, for a final gloss or satin coat on the surface.
