I am preparing to finish a red oak chest of drawers that I build. I will stain and seal the exterior of the chest, but would like to keep the look of the naked wood on the interior of the drawers. My question is, should I use a clear sealer on the drawer's interior, or should/can I leave them as is? My concern is that with the high humidity in my area (S.E. Virginia) , I will have moisture intrusion problems.
