GTechniq - Car Care Products - C1 Crystal Lacquer Plus - 30 ml Description C1 Crystal Lacquer + is a new and improved version of the previous C1 Crystal Lacquer. C1 + chemically bonds with paintwork to become the new surface layer of your vehicle. The strong bond gives unbeatable resistance to UV, dirt and water making the surface highly scratch and swirl resistant and much easier to clean! Gtechniq C1 Crystal Lacquer is different than other coatings because it bonds so tightly that it actually becomes the functional surface of your vehicle’s paintwork. In fact, Gtechniq C1 Crystal Lacquer lends part of its molecular structure to the surface molecules of the paint creating a covalent bond stronger than other sealants can even come close to forming.
