Just cut the pine for my build, unfortunately didn't have access to cedar. It will be on cinder blocks so no ground contact, and I am planning a metal roof. Would like to finish the outside to protect it from the elements, what would you recommend? Not sure if food safety comes into play if it's on the exterior, but if so I want that in consideration. I was planning on the interior being unfinished, but if there are any different opinions I would welcome them as well.
