I have a set of wheel I use for cold wet whether before I toss on my snows that I had Powder coated work well but as always be careful putting them on the car as the Powder coat can chip and with a dark color over a light metal it is noticable but a dab of touch up paint does ease the pain from 5 feet
If you are doing the prep work just make sure they are good and clean of all dirt and old paint..
