Good job. You can seal the ends with many things including Elmer's glue(yeah the white that kids use to eat in school), polyurethane in a spray or out of the can with a brush etc. and even paint. Seal the ends asap and then work on it as time permits as far as removing the bark. Seal the ends again if they need it after a couple days. Your staves will retain moisture longer if you leave the bark on. I work the bark off of hickory either the same day or soon after. Good luck, Tracy
