What would you guys recommend on the center caps on my chevy truck wheels? For the regular wheel I used Meguire's chrome wheel cleaner, and then mothers chrome polish, but am not sure if I should put a coat of Klasse AIO on or not. I think I need to remove the center caps, wash them in the sink and coat the plastic fake lug nuts with mothers "back to black" or something. Obviously it wouldnt be something I do all the time, but would a few times a year for "spring cleaning".
