Using this AUDI LZ5L/Q5 touch - up paint kit is a breeze. First, clean the area where you'll apply the paint. Make sure it's free of dirt and debris. Then, shake the paint well according to the instructions on the bottle. Apply the paint in thin, even coats, waiting a bit between each coat for it to dry. For best results, use the clear coat kit if you've chosen it. Just follow the same process as the paint. As for precautions, remember that the color might be a little different from your car's actual paint because of fading. Always test a small area first. When it comes to maintenance, keep your car in a shaded area as much as possible to protect the paint from UV rays.
