I color matched the Foliage Green furniture with fast dry auto paint. I believe it's just lacquer based, it comes off easily with spirits. I used Matte Clear Krylon to finish, as it is a protective overcoat and reduces shine.
Use solvents to prep clean the anodizing, and DON'T remove it, as it is the recommended and preferred primer on aluminum for commercial heavy duty use. Plus, when the paint does get worn, it stops at the milspec anodizing, not a shiny sanded aluminum bright spot that constantly leaves black marks on everything.
What I used can be stripped with a couple of pints of thinner, and it's still good to go, not a part in white needing another coat of paint, or $80 and eight weeks at an anodizer. No, I don't know what some were thinking. These days, it's IS cheaper to just buy another stripped lower or upper compared to that. Must be Rollmark Fever.
