I have recently rubbed through a plastic box which was left midway and it scratched my car along with another rack which helped it scratch my car.
My car was recently fully painted, I am looking to get this patched, the mechanic said there's a dent and requires full panel coating, although there's no dent and I felt he just want to overcharge me.
My question is whether I can use spray paints, available online and get this patched. Thanks in advance
