Gtechniq Crystal Serum Light (CSL) is a professional-grade ceramic coating that forms a hard, durable protective layer over your vehicle's clear coat, delivering long-lasting gloss, chemical resistance, UV protection, and scratch resistance that wax and spray sealants simply cannot match. The coating bonds chemically to the paint surface, providing up to 5 years of protection when properly maintained, with a level of gloss depth and clarity that transforms the appearance of any vehicle.

CSL protects against UV damage, oxidation, road salt, bird droppings, tree sap, industrial fallout, and environmental contamination. The hardness of the cured coating also significantly improves resistance to wash-induced swirl marks, making every maintenance wash safer for the paint underneath. Use it standalone as a complete single-coat ceramic system, or pair it with Gtechniq EXO as the topcoat for extreme hydrophobic water beading and an even more durable multi-layer system.

If you are looking for the best professional ceramic coating for cars that delivers years of paint protection, a Gtechniq ceramic coating for long-term gloss and swirl resistance, or the most trusted semi-professional ceramic coating system available to detailers and car enthusiasts, Crystal Serum Light is the product that consistently tops the rankings. Available in 30ml and 50ml.
