The front lip protector kit is designed to cushion the lip spoiler from direct contact with the ground and not completely prevent damage. When entering or exiting steps, please use carefully at a low speed. If the front lip is brand new, it is not a problem with degreasing, but if there is already scratch, please lay flat with sandpaper and degrease. Before installation, please temporarily apply it and check the installation location before working. This product is a consumable item, so please be aware that depending on the amount of wear and tear you may need to replace the product accordingly.
