Water spots on windshield

[abl1111]

FYI

Since my resto (10) years ago, including windshield glass, I've noticed really bad water spots on my windshield and side windows. Really bad. Nothing removed them. I tried muriatic acid, CLR, a few 'specialty' products. Even a razor blade. Nothing even dented it.

Except one thing; a compounding wheel with a wool pad and 3M heavy duty, compound… It did it fairly easy. Only area that still has the spots are the lower pcs of glass where I cannot reach with the wheel.

Hope this helps someone. I'm going to use RainX from now on.
