My car had a nasty film on the inside of the windshield on delivery, in spite of everything else being pretty spotless. Not sure how the SC missed it, but a good cleaning worked wonders for the glare, both into the sun and at night. I got to thinking, this stuff is probably still up there behind the plastic cover, affecting the camera. I'd like to pop it off and see if cleaning makes any difference with some of my AP anomalies. Anyone try this, and did it make a difference? Is it easy to do?
