I put a black epoxy on bare metal, base coat was a red oxide lacquer, used a piece of a sponge with black enamel, very thinned black with a little red enamel mixed, and brown with a little red enamel thinner heavily. I think a little less is better it got busy very fast. The left end of dash has a little less and looks better. Just dab the red oxide with the black and black mix looks best. Practice on some sheet metal scrapes. Used a sanding pad, then clear coat makes it pop. Zeke
