Using the AUDI LY1G Citrus Yellow touch up paint kit is easy. First, clean the area you want to repair thoroughly to remove dirt and grease. Then, shake the paint bottle well. Apply the paint in thin, even coats, waiting a few minutes between each coat. For the best results, you can use the included tools in the kit. When using the clear coat (if you've chosen the Clear Coat Kit option), follow the same process. Keep in mind that the color might vary a bit from your car's actual paint due to fading. Store the paint kit in a cool, dry place away from direct sunlight. If you have any issues during the repair process, our professional customer service team is here to help.
