Using this AUDI LX5H/2D Navarra Blue Metallic touch - up paint kit is easy. First, clean the area where you want to apply the paint. Make sure it's free of dirt and debris. Then, follow the instructions in the kit to mix or prepare the paint if needed. Apply the paint carefully in thin layers, waiting for each layer to dry before adding the next. Remember, the color might vary a bit due to paint fading on your car. When it comes to maintenance, keep the paint in a cool and dry place. Avoid exposing it to direct sunlight. If you choose the Clear Coat Kit option, apply it after the touch - up paint has fully dried for better protection and a nicer finish. If you have any issues during the process, our customer service team of professionals is here to help.
