you can either debark and seal the back or leave the bark on and keep indoors away from any bugs, although i have never actually had any elm staves eaten by bugs, best to be safe. either way seal the tips. if you want to work it down some go for it but the thinner it is the greater the risk of it twisting as it dries. i have had some stay perfect and other that twist every which way to sunday. looks like a nice piece than should yield a dandy of a bow! good luck with it- Ryan
