Fossil Prep Question

[Mike Everhart <mjever@xxxxxxxxxxxxx>]

All

I am in the final stages of preparation on a large (1.2 m) mosasaur
skull from the Smoky Hill Chalk (Late Cretaceous marine, Western Kansas,
U.S.A.).  Skull is in excellent condition and mostly articulated
(crushed laterally).  Bone is dark in color, dense and has good
porosity.  The surface of the exposed bone has been cleaned by
microblasting (sodium bicarbonate) and is finely detailed.  The specimen
is being prepared for museum exhibit in Kansas (glass fronted case, low
humidity, room temperature year around, with no other special
conditions).

My question is this.....does anyone have any recommendations for
coatings or other prep to preserve the specimen for a long term, low
maintenance exhibit?  Teeth and a few areas have been treated with
Paleobond but I do not want to detract from the natural appearance of
the bone if possible.
Thanks!
