I have some water spots on the windshield that I've been trying to remove. I've tried using Optimum MDR on it, but they're still pretty obvious. Anyone have tips or another product I can try? Thx
I have had pretty good luck with M205 and a cutting pad. If its etched really badly you may need something like the Nanolex glass polish but I think there is some expertise involved so as not to distort the glass. It needs to be polished very evenly.
