Using this Audi touch - up paint kit is easy. First, clean the area to be repaired thoroughly to remove dirt and grease. Then, shake the paint bottle well for at least a minute. Apply the paint carefully to the scratch or chip, using the included applicator. Make sure to apply thin, even coats. Let each coat dry for the recommended time before applying the next one. As for the clear coat, if you've chosen the Clear Coat Kit option, apply it after the paint has fully dried. This will give your car a nice, glossy finish and protect the paint from UV rays. Remember, due to paint fading on your vehicle, the color might look a bit different from the actual paint on your car. For maintenance, keep your car clean and wax it regularly to protect the newly repaired area. If you have any problems or questions during the process, don't hesitate to contact our customer service team.
