"Goo" takes a long time to cure fully but it does stay rubbery.
Exposure to heat (like a hair drier) will cure it faster. I was
surprised to see that (in atleast one in-depth test series) Gorilla Glue
produces a very weak bond, especially on wood (yellow carpenters glue is
much better). Good ad campaign though, got me to buy a bottle.
