12ft doug fir marine plywood skiff. Seams taped with 6" 6oz cloth and epoxy. As an after the fact thought...Can I cut some 6oz cloth the size of the boat bottom and lay it across the bottom of the boat and epoxy this thus connecting it with the taped edge overlap. In effect the bottom and 3 inches up the sides of the boat will be fiberglassed. She is not yet painted just taped.
