Thanks, that was my thought about paper towels, no sand. Why would
anyone go to the expense?
Glass is indeed hard, but I think some of the early lens coatings
weren't so hard. Someone will probably have a bit of history on that issue.
Regarding my comment about using rubbing alcohol and paper towels on
my eyeglasses, I pay extra for what they call a "hard coating, for
protection". Hope I am paying for something useful. (I hope that is
either in addition to, or is part of, the anti-reflection coating I
also pay extra for).
