Permanently patch your equipment with Porta-Patch, the UV light-activated fiberglass reinforced self-adhesive repair patch. It works on portables, holding tanks, trailers, pipes, and more. Cures in 15 to 30 minutes in sunlight (or five minutes with our RV flashlight) and can adhere to wood, fiberglass, or metal. When cured, it is rock-hard, rot-proof, waterproof, and can be drilled, sanded, or painted.
