All sheet goods - walls, floors, and roofs, are galvanized ring shank. All PT, including bottom plates, is galvanized. Any exposed framing - decks for example - are HDG. Coated sinkers for unexposed general framing - they are not coming out.
Edit: Lots of stainless roofing nails and box after box of stainless screws, for most exposed stuff. The fog around here kills everything else, pronto.
