Using this HYUNDAI VU2 touch - up paint kit is easy. First, clean the area you want to repair with a gentle car cleaner and dry it thoroughly. Then, shake the paint bottle well for about 1 - 2 minutes to ensure the color is evenly mixed. Apply the paint carefully to the scratches or chips using the included applicator. Make thin, even coats and let each coat dry for about 15 - 20 minutes before applying the next one. Remember, the color might vary a bit from your car's actual paint because of fading. Don't use the kit in extreme weather conditions like very hot or very cold days. For maintenance, keep the kit in a cool, dry place away from direct sunlight. If you choose the Clear Coat Kit, apply it after the paint has fully dried. This will give your car a nice, glossy look and protect the paint from UV rays.
