The Shoe Goo had a much smaller effect. Sorry for the mis-information.
It only took 24 hours for my memory cells to kick in.
Bob W. I tested rubber cement and shoe goo by placing a drop of each on pink
foam. I was looking for something that would glue the foam together
and dry fast. Rubber cement dissolved the foam right away. The shoe
goo didn't do much, but I should have looked later. After a few
minutes, the shoe goo dissolves the foam way too much to use it as a
glue, but not quite as much as the rubber cement did.
I found this out today when I tried to glue another piece of foam to
the mold I'm making for my cooling plenum. I retested the drops of
shoe goo and rubber cement on another piece of foam but let them sit a
little longer. The rubber cement dissolved almost all the way thru a 1
inch thick piece of foam. The shoe goo ate about 1/2 or 2/3 of the way
thru, but left a film of shoe goo over the "pit". The shoe goo dollop
may have been smaller than the rubber cement dollop.
So far I've successfully stuck the foam together with silicon bath tub
caulk and 5 minute epoxy. I also filled the voids with the
poly-urethane foam that comes from the hardware store in a spray can.
This stuff sticks to almost everything. BTY, shoe goo does not dissolve
poly-urethane foam.
