I used GRIOT`s polished, then sealed ALL of the glass on my F-150, and did just the windshield on our Sport Trac. Was a bit of work, but am hoping it was/is worth the effort.

Will do the remaining windows, and moon roof on the Sport Trac when it quits raining, (maybe by the end of the week), and THEN, I have the wife`s F-150 to do.

From what I can see, it sheets the water off as advertised. Hope it lasts !!! LOL
