Gorilla glue has gelled in an unopened container stored upside down after about

Unscrew the cap and you're ready to go (or not, if the stuff has set up).
However my experience has been variable, with some gorilla glue lasting a long
time after opening and other stuff totally failing. I think the only answer is
to use it frequently, or put up with a lot of waste. It is clearly to the
advantage of the manufacturer to have the stuff not last. Urethane glue is
really what you want in some cases (not too many), and so I put up with it.
