Cosa tratta questo video

Repairing fiberglass hull damage from only one side requires a significantly wider taper than a standard two-sided repair to ensure structural integrity. When access to the interior is blocked by molded liners or foam, grind the damaged area back to a clean edge and create a taper ratio of 18:1 or 24:1, rather than the conventional 12:1. For a hull approximately 1/8-inch thick, extend the taper at least four inches beyond the damage perimeter.7:38 Use 1708 biaxial fabric for structural strength and 1.5-ounce chop strand mat for surface stabilization and cosmetic finishing.8:12 Laminating polyester resin allows for subsequent layers of polyester-based fairing compound or gel coat to bond without additional sanding, provided the resin remains in its tacky state.14:14 After laying the glass, fill low spots with a fiber-reinforced structural putty, then apply a wax-additive gel coat or PVA to ensure a full cure.14:08 Final fairing requires sanding the perimeter first to blend the edges before addressing the center.17:46
