I'm thinking of using G-P "Plytanium Dryply" as roof sheathing. This
roof has an 'open' overhang, where the underside of the sheathing is
exposed. The plywood would be installed with the coated (red) side

Nope. Per G-P e-mail,
"DryPly cannot be painted as the water repellant waxy emulsion will not
allow paint to adhere to the board properly."

Oh well.
