I wasn't sure based on the OP description of the paint what he/she was seeing or feeling. Personally, I did have a one foot section on my left side of my trunk top and rear trunk door that was extremely rough. Like a light grit sand paper feeling! I didn't notice it until I came home and was hand washing the car. From just looking at the paint it looked ok? Pearl white hides everything. But it defiantly had something on the paint that the wash didn't remove. Clay bar pulled it off with some elbow grease work. It was defiantly not envirmental fallout or rail dust. Anyway just my .02. Best of luck.
