Using our AUDI LY3H/H1 Laser Red Touch - Up Paint Kit is easy. First, clean the area where you want to apply the paint thoroughly. Make sure it's dry and free of dirt and debris. Then, follow the instructions in the kit to apply the paint. Use the provided tools to carefully cover small scratches, stone chips, or other paint imperfections. Remember, because of vehicle paint fading, the color might be a bit different from your car's actual paint. For a better finish, we recommend choosing the Clear Coat Kit option. After application, let the paint dry completely. To maintain the painted area, avoid washing your car for at least a few days. Also, try to park your car in a shaded area to protect the paint from UV rays. If you have any questions during the process, our professional customer service team is ready to help.
