Stop settling for temporary waxes and sealants. Gtechniq Crystal Serum Light (CSL) is the gold standard for detailers who demand professional-grade results without the red tape. CSL offers 80% of the performance of Gtechniq's professional-only Crystal Serum, providing a high-gloss, ultra-durable finish that elevates your service and builds client trust.

Engineered for precision and longevity, this 9H-rated ceramic coating forms an incredibly tough, chemically resistant, and hydrophobic barrier. Whether you are protecting a daily driver or a high-end garage queen, CSL delivers a slick, swirl-resistant surface that makes future maintenance effortless. When your reputation is on the line, choose the coating that delivers consistent, shop-proven performance.

Key Benefits:

• Professional Durability: 9H hardness provides lasting protection against light swirls and environmental contaminants.
• Optically Clear Gloss: Enhances paint depth and clarity, leaving a finish that looks better than the day it left the factory.
• Advanced Hydrophobicity: Repels water, mud, and grime, keeping vehicles cleaner for longer.

How to Apply:

• Prep: Thoroughly wash and decontaminate paint.
• Correct: Perform paint correction to remove swirls (the surface must be perfect before coating).
• Apply: Apply CSL in a cool, well-lit environment using the included applicator for an even, glass-like finish.
