Had my car parked outside a friends house this afternoon, came out to find it had been scratched all down the passengers side of the car about 5 times, each scratch was going from the wing mirror to the rear panel so they were very long scratches, luckily managed to pretty much get rid of all the scratches using scratch remover and alot of t-cut, however in certain light you can still see the scratch marks very faintly, any ideas how i may be able to get rid of them totally???
