Hi All,  Craig Brougher has written an article titled "Using Gorilla
Glue" that you might find eye-opening.  In the article he explains
some of the properties of the glue and why it should not be used for
various kinds of repairs where the transmission of sound is involved.
The article is at http://www.player-care.com/cb/gorilla-glue.html

Musically,
