My favorite plywood is "form ply" or "balcony plywood". The paper face and almost solid core seems to last along time when exposed to the elements. I have made raised panels out of it for shutters on windows when the width required exceeds 16 inches. I find glue ups of solid wood weather poorly and expansion/contraction problems occur above this width. With proper backpriming and good paint I have seen no problems in the 20 years I have been using it. Good luck George.
