I allowed my Fenix TK11 to roll around on the garage floor recently, and for my stupidity, it scratched off the anodizing around the bezel and the rings just underneath. I've tried Birchwood Casey's "Aluminum Black" and that didn't work so obviously the body isn't aluminum. Anyone have a recipe for touching up scuffed anodizing. A magnet doesn't stick to it so gun blueing won't work, thanks.
