I have been thinking about doing something similar, but with the cup holder closed and then mounting in that spot.

 

I use Invisible Glass from Stoner. You buy it a Pep Boys and Wal Mart. You can also try Rain-Xing your windshield. The easiest way to do it is buy the Rain-X windshield wiper fluid.

 

yeah tried it and doesnt work im thinking about put in a insurance claim for a cracked one or large rock chips

 

My windshield is so sandblasted, it sucks! It is so hard to see out of at night. There is a small crack, so hopefully during the Winter, the crack will grow and insurance can replace it. If it is smaller than a dollar bill, they will "repair" it.

 

I've never noticed these water spots ya'll speak of, but now i'm afraid to look lol.
