What this video covers

Removing old bottom paint and improper topside paint from a transom requires 40-grit sandpaper to reach bare fiberglass or original gel coat, as finer grits clog quickly.3:59 Uneven surfaces and voids, identified by a higher-pitched sound when tapped, indicate poor previous repairs that require grinding down to solid material.7:40 To fill a quarter-inch deep void, six layers of 1708 biaxial fiberglass cloth and epoxy are necessary, though five layers followed by fairing compound often provide a smoother finish.9:16 When fitting stiff 1708 cloth into tight stringer extensions, sanding the thickness of the fiberglass can increase flexibility.13:23 Total Fair compound serves as an initial fairing agent to level the surface for a watertight seal.6:04 Pencil marks are preferred over permanent markers for layout, as marker ink can bleed through subsequent primer and paint layers.6:40
