I'm building a tortoise shed using plywood. I'm not a carpenter, so my shed is sort of like the house that Jack built. I'm going to put either metal strips down the corner seams - long strips of metal shaped in an 'L', or wood, sort of like what you would use for base boards. I'll attach this with finish nails, but I also want to put a bead of some sort of either adhesive or grout-type stuff. What would be best to use for wood on wood, or if I decide on metal (if I can find what I want), metal on wood?
