    Hi, I use Gorilla Glue or West System Epoxy for this. Both work well, but with Gorilla you have the expansion and seepage issue as it expands 4 times the volume as it cures.

    +1 on gorilla glue - it's what I use, but be watchful of the expansion and I typically use clamps.

    I use the Gorilla glue as well with a healthy dose of water. Spread glue sparingly on one piece and flood the second with water (and I mean FLOOD). clamp together....white beads will appear quickly. The glue will be set in about 1/2 hour when it looses it's "stickiness". Use a putty knife to remove the "beads". Don't wait!!!!! If you do, the glue will tear out some of the foam along the joint when you try to remove it.

    +1 for Gorilla Glue. There is a low expansion version but I clamp.

    The water leaves a softer glue line that won't show when sanded or blasted...... a little side benny. Joe
