I'm with Colbs. Plain old Elmer's Glue-all (A.K.A. "white glue"). It's simple, easy to clean, gives you time to make adjustments to get things lined up, and it's cheaper than pretty much every other glue out there.
As for the resin, bondo, and fiberglass cloth/mat for the hardening and reinforcing stages, you might find them at a hardware store, you will almost definitely find them at an automotive store, and you're very likely to find them at Walmart or other department stores in the automotive section. Pretty much the same for primer and paint.
But for future reference, this is the kind of question that should be asked in one of the "Help" threads, such as "Help for Pepakura" or "Help for Misc." rather than starting a new thread just to ask a question. Keeps the forums less cluttered and more organized that way, so people don't have to scroll through page after page of "one liner" threads to find things like builds, models, and tutorials.
