Any suggestions on getting out water spots on the windshield and paint with out going to a professional detailer? I just moved into a new home, finally a garage for the R, and the water has alot of calcium which I think is leaving more than the usually water spots. I normaly was the car early in the morning or late in the after noon to make sure it isn't in heat of the sun and dry it off in the garage. Any suggestions or comments welcome.
