Using this touch - up paint kit is a breeze. First, clean the area you want to repair thoroughly to remove any dirt or debris. Then, shake the paint bottle well for a couple of minutes. Apply the paint carefully to the small scratches, stone chips, or paint imperfections using the included applicator. Make thin, even coats and let each coat dry according to the instructions. For an even better finish, consider using the Clear Coat Kit. Just apply it in the same way after the paint has dried. As for maintenance, keep the kit in a cool, dry place. Remember, because of vehicle paint fading, the color might not be an exact match to your car's actual paint.
