Using this touch - up paint kit is easy. First, clean the area with scratches or chips thoroughly. Make sure it's dry before you start. Shake the paint bottle well for about 2 minutes. Then, apply the paint to the damaged area in thin, even coats. Let each coat dry for about 15 - 20 minutes before applying the next one. For the best results, use multiple thin coats rather than one thick one. When using the optional clear coat, follow the same process. Be aware that the color may vary slightly from your car's actual paint due to fading. To maintain the painted area, wash your car gently and avoid using harsh chemicals. Wax the area after the paint has fully cured to protect it from the elements and keep it looking great.
