When I purchased my car a few weeks ago I began to notice spots on the windshield, rear window, and sunroof. These spots appeared like small droplets of rain or specks caused by accidental over spray from a sandblaster. When the sun shines just right (every morning) on the windshield, it makes it hard to see. I attempted to use glass cleaner a few times to remove them but it was of no use. I took it back to the dealer and the service garage had a GM rep look at it the next day (he happened to be coming in). It was then deemed that it was probably clear coat over spray. The windshield and rear window are going to be replaced with GM glass under warranty (takes 4 days to arrive). Has anyone else seen this issue? It seems quite bizarre to me, but maybe it was parked near the body shop at the dealer it was transferred in from before I bought it...
