The time required to repair a scratch on a car door depends on the severity of the scratch. Here are the details: Minor scratches: If the scratch is minor and hasn't exposed the primer, simply polishing it with sand wax will make the scratch disappear. This takes at most 10 minutes. Deep scratches: If the scratch is deep, exposing the primer or leaving a deep groove, the process involves applying putty, sanding it smooth, then applying red putty, followed by a primer coat to check the effect, and finally spraying the paint (computer-matched for no color difference). This entire process takes about 1-2 hours and yields excellent results, making the repair virtually undetectable.
