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
