Your car has fading paint? I wish there was a product that would restore fading paint; Rub the lamp... POOF! There it is. Fresh PAINT! If you can't wash and polish and wax the car and restore it to it's original luster, it will have to be painted over.
I had oxidized clearcoat. I tried to buff it, polish it but it just started flaking off. I hope somebody knows of some product that works, because I wound up needing to paint the area the clearcoat came off of. When they post it here, you and I will be helped.
