You know how when you wear your dress shoes driving. The heels wear off the black finish and turn gray rubbing on the car mats. This can be quickly cured using the Exact Match black color card. Simply put a few drops of activator on the card and swirl it around. The black stain will come off the card and you then apply it to the back of the heel. It is permanent quick and easy to do. It also will do hundreds of repairs around your home or office.
