Gtechniq Ceramic Coating (Crystal Serum Ultra & Light)
Gtechniq is a British professional coatings brand whose flagship product, Crystal Serum Ultra (CSU), carries a 9-year manufacturer warranty when installed by a Gtechniq Accredited Detailer — the longest widely available warranty in the ceramic coating market. Both CSU and its consumer-grade counterpart Crystal Serum Light (CSL) cure to a 9H hardness rating and are used on OEM press fleets and Formula 1 vehicles.
What is Gtechniq Crystal Serum Ultra?
Gtechniq Crystal Serum Ultra (CSU) is the flagship professional ceramic coating from British chemistry brand Gtechniq. It is distributed exclusively to Gtechniq Accredited Detailers — a global network of installers who have completed Gtechniq's training and audit process.

- Crystal Serum Light (CSL): Available to non-accredited installers, 5-year warranty, same 9H hardness
How long does Gtechniq last?
Warrantied durability:
- CSU: up to 9 years (Accredited Detailer only)
- CSL: up to 5 years
Both are typically topped with Gtechniq EXOv5 — a hydrophobic top-coat — every 2 years to refresh water behavior.
How much does Gtechniq cost in the Phoenix area?
Approximate installed pricing:
- Gtechniq CSL, sedan: from $1,349
- Gtechniq CSU, sedan: from $1,800

Why Gtechniq's accredited detailer requirement matters
The 9-year CSU warranty is only honored when the installation is registered by an Accredited Detailer using Gtechniq's prep protocol. This is why CSU is not available on Amazon or through general detailing suppliers — the brand controls its warranty by controlling installation quality.
Who is Gtechniq best for?
- Owners who want the longest widely available manufacturer warranty (9 years)
- Buyers drawn to Gtechniq's F1 and OEM press-fleet reputation
- Vehicles that will not receive PPF but need premium standalone ceramic protection
