On the flat surface, start at the rear P5 and clamp one side section then CA glue. Don't glue to the tip, stop where you see the last clamp at the nose. Do the same thing on the other side. Insert the retrack windows with a little Titebond glue against P6. Fold the ply (no glue) over the nose and tape. Apply Titebond glue from the opposite side to P6, ply, and windows where they touch.
