First off, all scratches are unique with varying depths and severity. While we think Scratch Doctor® is magical, we want you to understand that there are certain scratches it won’t be able to remove. Your scratch might be too deep for it to be repaired without touch-up paint from a body shop. Secondly, you need to thoroughly work the product into the surface and create a certain amount of friction to activate the product. Simply applying the product to the affected area won’t repair the scratched surface.
