I think it was Lorna that glued thin sheet metal onto the plywood and then attached and caulked it in to the window space. It may be too late for you to do that, or not, but I thought I'd throw that idea out there. You would likely have to remove the plywood, glue on the sheet metal, then re-install. You could try to do it in place, but it would be much better to have the window frame overlap the sheet metal.
