A few weeks ago I was dismayed to find that someone had raked something alongside my car starting from the headlamp down to the rear light. It was obvious that it was vindictively done rather than accidental since the scratch dropped down to go below the mirrors and door handles. It looked an expensive job to put right, however I used some T-cut (Carplan) on it, then some metallic car polish, and after a lot of work, I was satisfied with the result.
