Crystal Serum Light (5 Year) is the prosumer version of the world-famous Gtechniq Accredited Detailer Crystal Serum Ultra. It offers 80% of professional Serum Ultra’s performance, but if applied incorrectly can be machine polished from your vehicles paintwork.

When it comes to adding gloss, resisting swirls, contaminant and dirt repellency, Gtechniq Crystal Serum Ultra and Serum Light are the pinnacle in paint protection.

Why use Gtechniq Crystal Serum Light?

Crystal Lacquer is a chemically bonding quartz (ceramic) paint coating.  It can bond to any type of gel coat, vinyl and all kinds of paint – eg clear coat, acrylic, nitro-cellulose, two-pack, solid paint, metallic paint, pearlescent, urethane, polyurethane, matte etc.  As C1 is a relatively thin and relatively hard it offers good swirl resistance but we recommend over coating it with either C2 or EXO to give your finish the ultimate in dirt and water repellency, gloss and slickness.  C1 is also resistant to temperatures up to 500 degrees celcius.

C1 Crystal Lacquer is extremely durable, as it actually becomes the functional surface of a cars 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.

On average, panels coated with Gtechniq C1, exhibited 50 percent less swirl marks than those coated with waxes or left uncoated.

Does it really last for years?

Yes! In fact due to it’s chemical bonding mechanism, Crystal Serum Ultra, Crystal Serum Ultra Light and C1 become the functional surface of your vehicle’s paintwork. In essence they bond permanently to your vehicle’s paintwork. Our stock answer to the question “how long does C1 or Crystal Serum Ultra last?” is that this is the wrong question. The right question is how particular you are about your paintwork and how carefully you clean your paintwork. If you are, like us, very very fussy about swirls etc. on your paintwork but at the same time have a poor wash technique then, even though Serum Ultra is highly and C1 is somewhat resistant to swirls, you may find that you will want your car to be repolished in a shorter period than someone who is less particular about swirls but uses a very good wash technique.

What's the best way to maintain my vehicle's finish once this product has been applied?

Even though, when compared to traditional waxes and sealants, this product is exceptionally durable, we recommend using products such as Gtechniq GWash or koch-chemie NanoMagic Shampoo
