Has anyone repainted their center caps? The silver paint is peeling off on three of my center caps and they look terrible. I'm debating whether to have them repainted at a wheel shop or just buy another set. I'm watching eBay for a set of four but really don't want to drop $100 or more. I'd paint them myself if I thought that I could match the paint color but I doubt that I'd be lucky enough to find an exact match. Any thoughts or suggestions?
