There are areas of your paint’s finish that see more abuse than others: on the edges of doors and the trunk lid, around the door handles, keyholes, at the hood latch, etc. What you need is a scratch remover. Mothers Scratch Remover works on any sort of finish to help restore high mileage paint and remove surface scratches. This is a true polish—be sure to chase it with the standard regimen of waxing to properly seal and protect.
