Unbeatable Performance From An Enthusiasts Nano-Ceramic Sealant.

Gtechniq Crystal Serum Light is the nano-ceramic sealant based on their professional only flagship coating Crystal Serum. Crystal Serum Light (CSL) has been designed with the car care enthusiast in mind.

Crystal Serum Light forms a strong chemical bond with paintwork to provide significant resistance to wash-induced swirls. It also provides an impressive resilience to extremes of pH, such as those found in some car wash products, traffic film removers, industrial fallout and environmental factors. Ceramic coating offers exceptional gloss levels and scratch resistance. This ease of use car ceramic coating can be used by all levels of car care experience.

Why Use Gtechniq Crystal Serum Light?

Protecting your car's paintwork is vital when stopping the introduction of swirls and other paint defects. Manual quick detailers or polymer sealants will only offer hydrophobic properties for a short period of time. Gtechniq CSL with its chemical bond not only will last years on the paintwork but also offers chemical and swirl resistance.

Can I apply this outside?

The short answer is yes, the long answer is to follow the instructions very carefully and ensure that the coating has the full 24 hours of dry weather to cure. Any water that gets onto the coating when curing could require machine polishing to rectify if etching occurs.

Best coating out there

I’ve used Gyeon, Carpro and Gtechniq for me is harder, lasts longer and maybe looks better as well.

GOOD but.... needs EXO

Overall a good consumer product. Tried the first time without EXO top layer, water spotting after ~6 months. Removed and recoat with CSL+EXO. Looking good till now. Do not use as standalone coat.
