I have a bison skull in need of some help. I have already glued the pieces back together with epoxy. I could not get some pieces lined up perfectly so I have some gaps. Nothing large maybe 1/8 inch at most. I am looking for some type of epoxy putty that I could use to fill things in. I want to leave the skull natural don't want to paint it so I need something that will match natural bone pretty close. Any suggestions are apperciated thanks.

White appoxie sculpt.
Available through taxidermy suppliers.

Thanks I 'll track some down.
