I don't recall that, but remember that at one point the EPA declared acetone to
be carcinogenic, and thus not readily available to the fiberglass industry.
Good science caught up with the EPA and acetone is now correctly identified
(except in the State of California where -- by law -- acetone causes cancer).

Does anyone out there know which year the EPA [or whatever the
bureaucracy was] made the boat builders change from the old "good"
fiberglass to the new "environmentally friendly" glass? I seem to
remember it being about 1972 [?].
