One more comment... DO NOT OVERDOO THE GLUE! This type of glue along with other's that are similar will EX--P-A-N--DD ALOT! Just run a small thin bead. Wipe off any excess right away and not with your fingers. This stuff is tough and not water soluable... actually it's the water in the air that makes this stuff activate.

Just do not use too much, and wipe off the excess. Don't run a bead of it on inside joints, this will make a mess of your box since this stuff expands. And let it sit overnight, next day will be rock solid.
