On the hull shown here, a layer of Awlgrip 545 finish primer has been sprayed on as well as a linear polyurethane topcoat (requested by owner). 8 The deck mold is waxed and sprayed, and similar laminating materials and process are used to layup the deck. The deck is then bonded over the flanges on top of the frames with a bonding flange around its perimeter (as shown in photo). 12 Blocks and cleats, control lines and other hardware are added.
