I've been working out my arm getting rid of water spots and looks like I may have some sucess with 'barkeepers friend' which has a gentle abrasive according to the manufacturer.
The streaks of water spots appeared when I applied WAUD for the first time over dealer's wax. It's on every window eveywhere, it's like the wax streaked down the windows and then dried and etched itself? This is only an 03 model.
You can't seen them when dry only during rain when wipers go over them or during drying.
Anyway, I will be doing another round of barkeepers on the windshield saturday, I've tried polishes like zaino,z1 glas polish ,detailers pride, and vinegar, dishwashing liquid sunlight and clay.
