I had bought a small bottle of Sumo, urethane glue about 8 months ago and
found a project for it today. I was shocked when I found the bottle to be
firm and, when I opened it the glue was more firm than usual. I got what I
needed and pitched the rest. That was a pretty expensive bottle
considering that I only got one use.

Finally, the question. What IS the shelf life of **unopened** urethane
glue? I had a similar sized bottle of Gorilla Glue and it lasted much
longer even though it had been used and there was air in the bottle. I
did store it on its head but still...

TIA,
Chuck

what does the label say? what does the person at the other end of the 800 #
that is on the label say? does the label say how to reconstitute it?

i recently had a tube of ge silicone fail to harden even though it was
before the expiration date. they replaced it for free.
