I really like Gtechniq G1. It's a little tough to get every smudge off at first and has a little bit more detailed application than most, but I've had great luck, especially never before treated glass. I also tried Detailers Pro Glass coating(for glass) on my moms Durango, and my dad said it's been really good too. It was very easy to use, you basically apply it and work it until it's gone, wait 2 minutes and lightly "buff" with a microfiber. you can find both on Autogeek
