Using this Hyundai Y8Y touch - up paint kit is easy. First, clean the area where you want to apply the paint thoroughly. Make sure it's dry and free of dirt and debris. Then, shake the paint bottle well for at least a minute to mix the paint evenly. Apply the paint in thin layers, waiting a few minutes between each layer. This helps the paint dry properly and gives a better finish. Remember, because of possible paint fading on your car, the color might look a bit different. Don't be alarmed if there's a slight variation. When it comes to maintenance, keep the paint bottle tightly closed when not in use. Store it in a cool, dry place away from direct sunlight. If you choose the Clear Coat Kit, apply it after the paint has fully dried for added protection and a nice shine. If you run into any problems during the process, our customer service team is here to help.
