I've got some burl wood coming unattached from the metal part on one of my doors; what's the best thing to use to glue it back?

I can't pull the whole thing off because it's starting to crack, and I don't have a lot of space between the wood & the metal (about 1/4") to work with.

Any ideas? I've got some decent industrial spray adhesive which I could probably squirt back there (much stronger than headliner stuff) but I figured I'd ask.

Maybe just plain old rubber cement?
