Recently I've noticed that there are white spots/lines on my rear windshield. It's hard to see and requires that you look at the window at an angle and not in direct sunlight. It does not affect my driving since you can't really see it when looking at the window straight on/through the rear-view mirror. <p>I tried to rub it out with a cloth and Armor All window cleaner, both inside and out, but it's still the same. I haven't had time to take it to the dealer, but some saleperson said that we have a coating on our windows and it could be the coating coming off. BS IMHO. <p>What's weird is, I saw the same thing on a 2000-2003 Camry that was parked next to me. <p>Has anyone else seen this on their cars? Any ideas?
