Gorilla Glue?

[UncleChester]

The standard Gorilla Glue brand glue is the common choice, but any of the expanding polyurethane based glues should be fine as well. I use Elmer branded "Ultimate Glue" with a raging blue minotaur on the bottle (much cheaper than Gorilla Glue).

Be sure to not get any on your skin.

Alright thanks for the advice. Would it work good with the Great Stuff Expanding Foam to?

Yes, particularly the polyurethane Gorilla Glue. The Gorilla glue we recommend (thanks to Johnny Farnen) is the "Dries White" stuff.

Depending on your application, superglue or regular aquarium sealant will pretty well.

Well I went ahead and got silicone. But I might use it in future projects
