Using our AUDI LY1B/F2 Brilliant Yellow Touch Up Paint Kit is a breeze. First, clean the area where you want to use the paint to remove any dirt or debris. Then, follow the instructions in the kit to apply the paint evenly on small scratches, stone chips, or other paint imperfections. When it comes to color matching, remember that because of vehicle paint fading, the color might be a bit different from your car's actual paint. That's normal. For shipping, we'll process and send your order in just one business day. As for maintenance, if you choose the Clear Coat Kit option, it will give your car a nice glossy finish and protect the paint from UV light. This will also help keep the color looking good for longer. If you have any questions during the process, just reach out to our customer service team. They're experts in auto body and car paint repairs and will be happy to assist you.
