I've been using Pinnacle GlassCoat for the last few months with spectacular results. I applied it on my car a couple of months ago and my wifes car just last week, I havent had a single water spot on any of the glass on both vehicles. I reapplied it to my car since i was doing my wifes car, i dont think it needed it but i went ahead and did it, we had a tropical depression/storm last week so i wanted to make sure I was covered.
I think the ultimate test for me is that I also applied it to my shower glass a couple of weeks ago and it's performing very very well. We have extremely hard water in Houston, typically if I dont wipe down my shower it'll spot in about 1-2 days. After about 3 weeks, I think just saw the first water spot, given that the shower is used at least twice a day during the week and 2-3 times on saturday and sunday, it's doing very well.
Yes, GlassCoat cost a lot more but this stuff goes a loooong way!
Good Luck
