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.

Abstract: Apparatus for windshield glass repair is provided. A cylinder having internal chambers is equipped with a piston head plunger at a top end and has a mounting device at a bottom end for securing a tight seal over a crack in a windshield. The withdrawal of the plunger creates a vacuum and allows for air to be pulled out of the crack, while a side stem in communication with the cylinder allows resin filler material to be introduced and forced into the crack. Air pressure is equalized by opening the side stem, whereupon the plunger can be depressed to force the resin filler into the crack. The mounting supports allow for quick connect and disconnect of the cylinder. The side stem obviates the necessity of removing the cylinder for re-filling of resin material whereby any length crack can be repaired without breaking the tight seal on the crack.

Abstract: An apparatus for repairing breaks in safety glass, such as that found on automotive windshields, includes a self-contained, small fixture which can be secured to the windshield and centered on the break. The fixture includes connections for applying a vacuum source for evacuating the break, and for connecting a self-contained and self-supported measured quantity of resin to the fixture so the resin will enter the break while the break remains under a vacuum. The introduction of the resin into the break is thus enhanced, because the break is under vacuum. When vacuum is released, pressure may be applied to the resin to force it into the break to completely fill the break and provide for a visually acceptable repair. Curing of resins can then be carried out in a conventional manner.

A separate sealing lip, being part of the diaphragm, encircles this immediate area on the windshield and completely isolates the second enclosure from the first enclosure. In the center of the device is a cylindrical passage that axially extends from the exterior of the housing into the second enclosure. A piston assembly can move in and out of the cylindrical passage to introduce the repair liquid into the conical cracks in the shatterproof windshield.

Abstract: A device for repairing windshield cracks. A cylinder includes a sealing mouth adapted to contain a quantity of filler material. The mouth with filler material therein is positioned over the crack opening. The cylinder includes a small cavity adjacent the mouth and a larger upper cavity.
