In the case of deep scratches on the bodywork to postpone the intervention of the body shop you can use the trick of the wax crayon because it protects the metal and prevents it from rusting.

Then take a wax crayon of the color as close as possible to that of your car to fill the scratch and remove any excess with a soft cloth.

For surface scratches instead of parking scratches, you probably won't need to go to the body shop.

Just use the polish and a soft wool rag to remove the rubbing paint.
