I recently had some body work done on my M3 due to an accident. I noticed the other day there is a fine mist of something on the windshield, which is very noticeable when the sun shines though at a low angle. The glare is pretty bad. It's like there are tiny dots all over the place. You can't see it at all during other times of the day. Upon further inspection, it's also on the outside mirrors and is visible when the sun shines from the rear of the car. I assume this is some residue from the body shop painting that settled on these surfaces. Clear-coat perhaps? Washing it with Windex does nothing. Is there a way to remove this?
