I'm almost to the point of a restoration of a pair of Mickey Thompson valve covers. They aren't a matched pair......one is bare aluminum, the other is the original black finish. Therein is my dilemma/question. It's definitely not a wrinkle finish, more like a semi gloss black paint that had some type of "grit".......sand or? sprayed on while the paint was still wet. Anyone have any ideas what the original finish is? Where to obtain an aerosol (preferably) of it? The original black one needed some cracks repaired (done) and needs the touch up. The all bare aluminum one had the same issues. It now needs the color treatment. Not wrinkle, I don't think it's the "camera body" finish either. What say ye.
