Using this touch up paint kit is a breeze. First, clean the area where you want to apply the paint. Make sure it's free from dirt, dust, and grease. Then, shake the paint bottle well for about a minute to ensure a good mix. Apply the paint carefully to the scratches or chips, using the included applicator. Apply thin coats and let each coat dry for a few minutes before adding another. For the best results, follow up with the Clear Coat Kit if you've chosen it. Just apply it in the same way as the paint. As for maintenance, try to park your car in a shaded area to avoid too much sun exposure which can cause paint fading. And if you notice any new scratches in the future, you can use the remaining paint in the kit to fix them. Remember, the color might vary a bit from the actual car paint due to fading, but our paint will still do a great job covering up those blemishes.
