Its starting to really bug me, especially since its a 2002 car. Its pretty faint, but noticable when looking at a bright street light or something through the winshield. I've heard sos pads can be used on the winshield, any other suggestions? Wax maybe?
Thanks

Removing etched (below surface) water spots from glass--- are caused by acid rain or industrial fallout causing a chemical reaction, if left for any length of time they will etch the paint film surface leaving a concave circular mark.

These can usually be removed using detailer's clay to remove any hardened surface deposits and then using Autoglym Car Glass PolishTM with #0000 synthetic steel wool or Iz Einzette Glas Polish, a random orbital buffer (speed # 4) and a cutting foam pad (LC orange or yellow) to level the surface.

Notes:
1.Do not use abrasive cleaner; glass polish or any grade synthetic steel wool on after market-tinted glass or you will probably scratch the surface.
2.For deeply etched water spots' in the glass surface, do not attempt to polish them out, consult an automotive glass vendor as glass used on later model cars is soft and thin (this may vary by manufacturer) due to weight / cost savings by vehicle manufactures and polishing could cause glass to crack.
3.Be cautious with polishes that contain abrasives like aluminium or cerium oxide as they have the potential to damage glass beyond repair.
4.Some windshields and mirrors have a tinted plastic coating or a blue tint that will scratch or be damaged, only polish or use synthetic wool on uncoated glass.

I've used Detailer's Pride Glass Restorer, it works great.
