I am replacing the seat wood in my sundeck on a Bryant 200. (1992-before 100% fiberglass construction)I have seen conflicting suggestions on pressure treated vs outdoor rated plywood. My concern is the warping of the damp pressure treated plywood for a wood section as large as the one needed for the Sundeck (I couldn't even find one that started flat prior to drying at Home Depot). Can anyone point me in the right direction?
