Using your AUDI LY8X/4J Havanna Black Metallic Touch - Up Paint Kit is a breeze. First, clean the area you want to repair thoroughly to remove dirt and grease. Then, shake the paint well for a couple of minutes. Apply the paint in thin, even coats, waiting a few minutes between each coat. For the best results, use a small brush for precise application. When using the optional Clear Coat Kit, follow the same steps. Remember, the color might vary a bit from your car's actual paint because of fading. Store the paint in a cool, dry place away from direct sunlight. If you're not sure about anything, just reach out to our customer service team.
