71 Demon hood scoop trim - underneath painted?

I noticed in the Classic Industries catalogue, they're described as painted argent silver and black on the underside of the lip, so so the PO must have polished them off I my car. I'm going to try cleaning them with acetone, and using a self etching grey primer before I hit them with the light argent. Anyone know of a good source of '70 light argent paint" I'll need it for my grill and bezels too.
