Any thoughts on using this brand on bear skulls, any mods that had to be made to secure skulls? On open mouth I've used wood glue to attach lower jaw,never had a problem.What do others use to attach lower jaws ?

Good question, it should work. As for the lower jaws, I have seen zip ties used to attach them, like when Skulls Unlimited ships them out. You might be able to use that method if you could find them in white. Otherwise, you might have to get creative

Thanks for the reply
