Detroit, MI area. Hardwood over 1X6s over full heated basement. AC
was only installed last spring - kept mid to upper 70s during the
summer. Have never had moisture problems in the past.


A lot of plastic products from "the old days" deteriorated over time, and
that might be all you're seeing. I had a nice aluminum camera case with foam
lining, circa 1973. About 5 years ago, the foam began turning into some sort
of god-awful goop the consistency of peanut butter. No liquids or other
substances ever came into contact with it.
