Using our AUDI LY1S/5R Cosmic Yellow Metallic Touch Up Paint Kit is easy. First, clean the area where you want to touch up the paint thoroughly to remove dirt and debris. Then, shake the paint well according to the instructions on the bottle. Apply the paint carefully on the scratches or chips, using the tools provided in the kit. You may need to apply multiple thin coats for a better finish. Let each coat dry completely before applying the next one. Regarding the clear coat, if you've chosen the Clear Coat Kit option, apply it after the paint has dried. This will give your car a nice glossy look and protect the paint from UV rays. Be aware that the color might vary a bit from your car's actual paint because of paint fading. Store the paint kit in a cool, dry place away from direct sunlight. If you have any issues or questions during the process, don't hesitate to contact our professional customer service team.
