Do I need to seal the inside of a storage bench?
Building a banquette/storage bench for the dining room (still have to add the back and some trim and such). Making it out of Baltic birch ply and will be painting the outside of it like a cabinet. Do I need to finish the inside with anything? Looks do not matter on the inside to me, but I’ve heard it’s generally a good idea to finish both sides of something. If so, with what?
