hey pearl,i've wondered the same thing.i made a few boo arrows and didn't seal them.mine still had the rind left on.they never warped and stayed straight.might have been the rind.i guess you could seal them just like any type wood arrow.hey ,but what do i know.i can't wait till someone chimes in because i am curious aswell.i am working on some tonkin cane and some hill cane right now.i might have to hold off until i get some info,steve
