Stoner Invisible Glass with RAIN REPELLANT - 22 oz. Trigger Bottle contains a protective agent that fills in the tiniest scratches and crevasses. This product has the same effectiveness and performance as the original Invisible Glass, but with an add bonus. When used, Invisible Glass with Rain Repellant will form a protective shield to repels dust and water enabling better visibility. When applied to the surface of a window, windshield, or glass surface, the product comes out in a light mist and clungs to the surface without running. It is easily removed with a clean towel or microfiber cloth - leaving a streak-free finish.
