Our paint repair is primarily designed to address chips, but it will work well on certain types of scratches and poorly on others. There are several variables that determine repair quality:Deep Scratches - Deep, narrow scratches (1/16" or less) down to the metal will usually hold paint. As our paint is instantly malleable (in this case, tacky, yet removable), there is some flexibilty in finessing the paint into place.  The various brushes in the kit also allow for more precise painting of scratches that can't effectively be repaired by our standard process.Wide Scratches - Wide scratches (1/16" or greater), gashes or other large defects will likely need to have the paint applied and left as is. Filling and spraying these types of damage is the only way to get a 'like new' repair. Light Surface Scratches - Generally these can be buffed out. If you can feel them with your fingernail, they might come out completely with some wet-sanding and buffing. Otherwise, our precision brush can be used to lightly apply the paint over the scratch and left as is. Key Scratches - We don't recommend buying our kit soley for fixing key scratches unless the vehicle color is dark, and the scratch is short and deep. A long key scratch on a light silver or gold car will show almost no difference, even if the paint completely fills the scratch. However, if you are not inclined to pay for a body shop repair, the special brushes in the kit will help you make the best repair possible. Vehicle Color - The color of the vehicle also determines the quality of the scratch repair. Darker colors always look better than light ones. A scratch on a black or dark red metallic vehicle will always look better afterward than on a light silver or gold one.
