I have a deer skull from a buddy that he had "porfessionally" done. (Euro mount). It is flakey and dull. This guy tried to, what looks like spray paint it with a pearl white paint and all of it is flaking off. It still looks crappy. I am trying to fix this other guys mistake. How do I .... 1. Remove the paint with out daminging the bone 2. harden what bone is left?
