Using this touch - up paint kit is easy. First, clean the area where you want to apply the paint. Make sure it's free of dirt, dust, and grease. Then, shake the paint bottle well for a few minutes. Apply the paint in thin, even coats, waiting a few minutes between each coat. For best results, follow up with the Clear Coat Kit if you've chosen it. When applying the clear coat, use the same technique of thin, even coats. As for the color match, remember that due to paint fading on your car, it might not be an exact visual match. This is normal. For maintenance, try to park your car in the shade as much as possible to protect the paint from UV rays. If you notice new scratches, you can use the remaining paint in the kit to fix them. If you have any problems or questions during the process, don't hesitate to contact our customer service team.
