Yeah, I was thinking of just lining the whole inside with cedar and make new shelves out of thicker cedar. The way my doors are though, they don't latch, there's a little rubber bumper on the door that leaves about an 1/8 inch gap between the door and the face. If I put some of that stick on weatherstrip on the door it might be more sealed but never as tight as a humidor lid. I don't know tight it needs to be. I guess as long as the humidity stays constant it wouldn't matter?
