Most scratch removers use harsh abrasives to remove layers of your car’s paint. This will, in turn, conceal the scratch by removing layers of paint much like sandpaper does to wood, dulling your paint’s surface. Scratch Doctor uses organic compounds and microemulsions to smooth the sharp edges of the scratch. It is designed to soften the edges of the scratch with each application without harming your car’s surface. And it will improve the appearance of even deep scratches, but if you can see the metal beneath the paint only a body shop can repair your paint.
