huge props to "Duplicolor Rim and Wheel Paint." They come in four colors: Light silver, grey metallic, black and clear. I've used this stuff on everything and it dries to a very hard finish, far better than every rattle can enamel I've used. The metal flake is pronounced and must be lightly sanded before clear. The clear is thick and hardy. NOTE: you respray inside an hour or after 7 days. Yes, 7 days. It has a 7 day cure time to harden. You can drive in a couple of hours, and it will be fine, but the chemistry really does use all that time to fully harden. I've used it for wheels, doors, fenders, skid plates, oil pans, transmission pans and body armor and if I have any excuse for a metallic grey or silver it is my go-to.
