Actually acids do not attack glass. Alkaline solutions will. There are
lots of things in the rain besides the nitric and sulfuric acids, and
I am not saying it wasn't the rain, just that it wasn't an acid. The
acids are highly soluble and won't form a deposit on the surface.

Depends on the acid. *Fluorine acid (hydofluuric acid) is what is used to
make frosted glass lightbulbs.

Also in plating, along with a bunch of other goodies... I used to work
with all the "rics". Maybe that's why.. oh, forget it. Anyway, if the
top is hard, could the guy buff it with the right buffer material and
abrasive or would it leave too many imperfections in the plastic to
see it in the weird lighting conditions on a boat?

No chance of finding a detectable ammount in rain. I had heard of
hydroflouric acid, but I thought it was irrelevant. The other zillion
acids do not affect glass.
