Check the listing for details. GTECHNIQ C1 Crystal Lacquer 50ml. Condition: New. Listed at 79.95 USD. C1 has been independently proven in the world's most respected weathering facility. As you can see in the YouTube video below, it offers the best gloss retention out of all products tested. Over a simulated run of 3 years in Arizona sunlight, a C1 coated panel lost half the amount of gloss as its next best competitor, and a third less gloss than the average score for all other products tested.As well as gloss retention C1 Crystal Lacquer is extremely durable, as it actually becomes the functional surface of a car’s paintwork. Also scratch-resistant, C1 forms a crystalline film which is extremely hard - this characteristic makes it effective at preventing minor scratching from poor wash technique on relatively soft automotive paint.
