Abstract

Abstract An improved method for the repair of fiberglass boat hulls by replicating surface textures on the boat hulls is disclosed. A laminar, dimensionally stable, flexible mold is formed having a negative impression of the surface texture to be replicated formed on one side thereof. The laminar, dimensionally stable, flexible mold then is placed atop a recipient boat hull surface and a layer of fluid casting material. Pressure is applied to the laminar, dimensionally stable, flexible mold to expel entrapped gas from the fluid casting material and to evenly distribute the flexible casting material over the recipient hull surface. The fluid casting material is cured, and the laminar, dimensionally stable, flexible mold is removed. A replica of the surface texture remains on the recipient boat hull surface.
