Step 5: Finishing your skull
2. Buy plain, clear nail polish and paint it on both sides of all of the skull's teeth. This will help to prevent the teeth from splitting in the future.
3. I like to spray my skulls with a clear semi-gloss wood finish. This may take several coats. This is not necessary, but I like the added gloss. You can also glue the lower jaw onto the upper part of the skull if you wish to & pose it so the mouth is open in a snarl.
