Using this AUDI touch up paint kit is a breeze. First, clean the area you want to repair with a mild car cleaner and dry it thoroughly. Shake the paint bottle well for at least two minutes to ensure the color is well - mixed. Then, use the included applicator to apply the paint in thin, even coats. Let each coat dry for a few minutes before applying the next one. When it comes to the clear coat, if you've chosen that option, apply it in the same way after the base paint has dried completely. As for precautions, make sure to work in a well - ventilated area to avoid inhaling fumes. Also, keep the paint away from heat sources and open flames. For maintenance, store the kit in a cool, dry place. If there's any leftover paint, seal the bottle tightly. If you notice any issues during or after the repair, don't hesitate to reach out to our customer service team.
