Don't laugh But when i painted my calipers black i found some Wicks Exterior paint in the shed :! . I thoght i'll just try it to see what the look would be like, before i went out bought some proper stuff. This what put on prior going to the Inters 05. And guess what they still black a glossy today. !amazed Just make sure you give the calipers a good clean before applying an paint.Remember Preparation, Preparation and Preparation
