Using this Hyundai touch - up paint kit is easy. First, clean the area with scratches or chips thoroughly to remove dirt and debris. Shake the paint bottle well for about 2 minutes to ensure a proper mix. Then, use the included applicator to apply the paint carefully to the damaged area, following the natural contours of your car. Apply thin coats, waiting at least 10 - 15 minutes between each coat. If you choose the Clear Coat Kit, apply it after the paint has fully dried. As for the color, remember that due to paint fading on your vehicle, there might be a slight color difference. Avoid using the paint in extremely hot or cold conditions, as it can affect the drying process. After using the kit, store the remaining paint in a cool, dry place.
