Using this Hyundai UD touch - up paint kit is easy. First, clean the area you want to repair thoroughly to remove any dirt or debris. Then, shake the paint bottle well for at least 2 minutes. Apply the paint carefully using the included applicator, making thin and even coats. Wait for each coat to dry before applying the next one. Remember, due to possible paint fading on your vehicle, the color might be slightly different. When storing the kit, keep it in a cool and dry place away from direct sunlight. If you have any problems during the process, don't hesitate to reach out to our customer service team for help.
