A sealer helps preserve the bone and mostly helps aid in cleaning, it seals up the pores of the bone so it makes dusting skulls off a lot easier.I use paraloid B-72. Its the same stuff museums use to preserve bone. I like a low gloss, like a satin. You can use pretty much any water white (non yellowing) clear finish.
Wasn't happy with how high the liquid was sitting on the skull, so had to put some "filler" in the pail. Now its sitting perfectly about 1/4" below the base of the antlers and filling the eye sockets. Looking good! I'm getting excited!
