Not having a credit card handy (meaning: I'd have to walk from where the
thought struck me, approximately 30 feet into the house), I spotted a
wall outlet cover in a misc hardware drawer that looked like a likely
candidate for spreading glue on some 4" boards. Poured on the TBII and
took a swipe with the cover across the board. Wow! Nice even coverage.
gotta love the curved edge of those covers. Try it some time--it's
not as weird as it sounds.

What "odd" thing have you spread glue with, that worked well?
