Greetings everyone,

I am about to have my windshield replaced and it occurred to me just
how serious the water spots are on my other windows.  It is as if they
are etched into the glass (probably are, through some chemical process
of which I'm unfamiliar).  How might one go about polishing glass so
as to remove those unsightly water spots.  Could I use jeweler's rouge
or something similar?  Another cleaning chemical, possibly mildly acid
based?

Thoughts and comments appreciated.

p.s.  I ordered my Cal-look windshield rubber from West Coast Metric
based upon my experience with them from about 15 years ago.  I
received it and the rubber looks good, and I know it's a bit late to
ask this question, but do you guys (non-gendered term) have any recent
experience with their rubber products?
