Dang Dalite, that really sucks! I have about 2500 miles and no problems like that at all. My thoughts are 1. Maybe it's that color, 2. Maybe they didn't complete one of the clearcoats on your car, or 3. Acid rain, or some such, like tree sap?
If I saw that I would have thought the person scrubbed with something too abrasive or detergent too corrosive, but that would mess up more than just those few places.
