Hey any of you had any problems with this? I got this truck and didnt pay any attention because when i drove it it was snowing and raining at the same time. Now when I get it and look real good it has hard water spots on the glass. Whats the best way to get this chit off my glass? I have already tried 0000 steel wool and light compound, Magic Eraser, Clay Bar, Vineger. Any more ideas? Im getting my windows tinted Sat and I know it will show up big time when I do that so im trying to get rid of it ASAP.
