I, too, am a great advocate of Gorilla Glue and I agree with
Eric Shoemaker in all regards.  I can make two small additional
suggestions.  Since it will harden in the bottle once opened,
squeeze the bottle before replacing the cap to exhaust as much
air as possible.  This will lengthen the shelf life of the stuff.
Secondly, buy it in small quantities because of the shelf life
problem.  Only buy large bottles when you know you are going to
use a _lot_ of the stuff.

Take care
