Using this touch - up paint kit is easy. First, clean the area where you want to apply the paint to remove dirt and debris. Shake the paint well before use. Then, use the included tools to apply the paint carefully on the small scratches, stone chips, or paint imperfections. Let it dry according to the instructions. Remember, because of vehicle paint fading, the color might be a bit different from your car's actual paint. As for maintenance, keep the kit in a cool and dry place. If you choose the Clear Coat Kit option, apply it after the touch - up paint has dried to get a nice glossy finish and protect the paint from UV rays. If you have any problems, just reach out to our professional customer service team.
