In January my A3 was keyed both sides front to back by school kids. The car went into a an 'Audi Approved' body shop and had both sides re-sprayed. The laquer on the passenger side ONLY now has 3 burn marks from bird ****. I always clean any off as soon as I see it, and when we go out to walk the dogs in the evening I always have a quick look over the car. The latest mark is a result of bird **** being on there for under 4 hours!! If I get bird **** on any other part of the car and wash it off there is no marks, it only seems to be the passenger side. Is it possible for the laquer to be faulty on this side? This may be a daft question but like most things are there different qualities of laquer available? I'm going back to the body shop as at this rate my car is going look bloody awful in another year. Up to the re-spray I had no marks at all on the paint work since last August, it too much of a coincidence. I really want to be forearmed with some backup info before I tackle them. Any info would be very much appreciated.
