Anyone have any experience with this stuff? I'm trying to replace the
old scuttle panel for access to my attic with a contraption that I am
trying to make out of some 2" (thickest I could find) foam board and
Masonite. Reason for doing this is that my bedroom closet gets very cold
in the winter, I ASSume because the ceiling is well insulated but the
panel is just very thin plywood. 2 questions:

1) It appears that in an effort to make a tight fit, I cut the foam
board just a little big. Is there an easy way to shave it down a little?
It doesn't "shave" well with a knife.

Not even with a "Stanley knife" with a new blade?

2) What do you use to glue it? I'm trying to laminate three pieces
together for better insulation (the bottom most piece will be hanging; I
cut it slightly smaller so it'll fit in the "jamb" area of the scuttle
hole. That one will be faced with Masonite for a finished appearance.)
construction adhesive isn't doing it (I put 8-10 dots on there.) Should
I just use more construction adhesive, or is there something better?

I've used "foamboard adhesive" in cartridges designed for a caulk gun.
Don't recall the brand.
