Hey Zac, It's Jon Boright. I have a few gallons of left-over end sealer (anchor seal from UC coatings) from my frame which you can have if you still need it. (sorry if this is too little to late). Also, if you are swinging through the Montpelier area, you can stop at "The Re-Store" and see if they have anything that'll do for corner protectors. I picked up a handfull of cardboard corner protectors (they look like they were originally used for packing some kind of heavy equipment) for about a quarter a piece.
Good luck,
Jon
