First and foremost, I am going to apologize for the crappy picture. It was taken with my phone and it was the best that was available at the moment. For as long as i've had my car (little over a month) I have noticed these little (for lack of a better word) "water spots" around the surround of the rear window. In the picture, you can sort of see the blueish green marks on the bottom left-hand corner of the glass. Is this normal? Should I get something checked out or fixed? Thanks!
