These so called miracle scratch removers are a joke. The only thing that removes scratches is a product with an abrasive, or you can fill them in by repainting or re-clear coating. McGuiar's Scratch-X works well on the small stuff, and their Ultimate Compound works well for the bigger stuff. The only way to fix scratches that are down to the primer or the metal is to replace the paint. These miracle products won't work.
