Can you point me to a few hundred other people who are having the same problem,
or is it only you?


Larry's unbalanced rants have resulted in my having him plonked! (kill
filed) so that I do not see his posts. But I do see his driveling
quoted in replies.

I'm beginning to believe that if he has ever actually seen some
corrosion it is a result of his insistence on plugging up drain/vent.
Doing that traps the moisture from condensation moisture inside, it
can't ever get out. He may be suffering from a self-inflicted wound. :)

For the record, as a former machinist/gunsmith/welder, the term "pot
metal" is commonly used to refer to the various Zamak
(zinc/aluminum/magnesium/copper) alloys used for hot chamber casting
complex shapes. It is very widely used and was once much used on
automobiles for mirrors, head and tail light housings, trim pieces, and
the like.

I once made a simple mold for an welder so he could cast his own Zamak
filler rods for use in TIG welding vintage auto parts. The welder used
to get obscene amounts of money for repairing and filling holes in parts
for vintage car restorations.
