Here's the story
So last summer when I was home from college It was like 105+ degrees one day (Virginia Beach VA) and my mom had the guy that usually washes her car do mine. When I went outside he was washing the two cars at the same time (shitty). I noticed that there were soap suds all over my windshield and the windshield itself was kind of steaming. I had applied Rain-X a couple of weeks before hand and saw that the suds were beading up in the normal Rain-X fashion.
So since that day, anytime there is any condensation, moisture, rain, or even in certain lighting angles and at night (street lights absolutely suck), I can see watermarks and it almost covers my whole windshield (kind of look like stretch marks). Its gritty to the touch on the outside and feels like sandpaper. I really don't know what it is.
I've tried every Glass cleaning product I can get my hands on. Invisible Glass, 20/20, etc. I even went to a local glass supplier and got one of their employes to look at it. He told me to buy this abrasive glass cleaner. I did and used it, again NO Luck. Vinegar and old newspapers, NO Luck.
Anyone ever heard of this or have any suggestions?? (other than a new windshield)
