Almost ready to skin the Hatch - Question

Okidoki the excitement is growing strong,,,, Us boys are getting ready to skin the hatch ... went and purchased some real nice Baltic Birch Exterior Marine Ply which is 1.5 millimeters in thickness and the exact length and width... so no need for cutting .. (precut ) I guess its called...
Is there a certain way we should proceed now except use caution...
Do we use small screws to hold the ply in place during the drying of the glue? or what do you folks recommend?
Also purchased Marine glue that we were told by the dealer will work very well for this purpose...moisture resistant as well...It sets fairly fast it states...
Just had to ask before we begin so we dont make any mistakes on this..
