My son is an idiot.
He decided to wash his car (dark blue Fiesta) with a little washing-up sponge that had a green nylon scouring pad on one side.
The paintwork is now covered in swathes of tiny scratches.
What can we do to get the shine back? Is it just a question of T-cut and elbow greae, or is there some magic method used by car dealers that restores the shine?
He is a typical teenage student, so if it involves too much hard work then It will probably not get done....
