Dan,
The material is polyurethane foam and the warning on the can applies to
the flammable vapors which are present in the curing process.  The stuff
cures in a few minutes and I tested it some 30 hours later.  So I think
my test is ok here.  But to be sure, I am coating it with some
undercoating which should be an extra measure of security.

But thanks for the words of caution.

Regards,
Joe
