Paint stripper damage

I had my plane painted recently, he did a decent job except for
allowing his masking to slip on all windows and windscreen. This
allowed the stripper to damage (cloud) spots on the plexiglas.
It appears to have penetrated the plastic so the damage may be deep
rather than a surface problem.
Now - before someone yells "sue the SOB" he has already closed shop and
evaporated. Yes, I know where he lives but I don't know where he
works. Incidentally does anyone in centeral Texas know where Pat Vela
is working? I need to garnish a paycheck.
Back to the subject. Has anyone dealt with a similar defacement by
polishing out a few spots? I replaced the windscreen but would like to
try something cheaper and possibly easier for the side windows.
Thanks, Leo
