You want the polyurethane stuff ("original Gorilla glue"). It's water activated, so it actually works best when the wood is damp. The glue expands into the wood, so that's why you see the foaming. I'm pretty sure TM uses the polyurethane glue anyway.
You will also want to clamp the portion of the shell you are gluing between two wood pieces or else the glue will tend to push the aluminum skin outwards instead of pushing the glue into the wood. I hope that makes sense. I may have a picture of how I set up my clamps, but I can't look until I get home.
