Gtechniq Crystal Serum Ultra is a different league of ceramic. Where standard "9H" coatings work via hardness, CSU adds UV resistance, acid rain tolerance, and clear-coat preservation. The manufacturer — British Gtechniq — sells it only to certified partner studios, which guarantees install quality. Manufacturer warranty: 9 years (through certified installers). Here's the pricing.

What else affects the quote
Vehicle size. CSU is priced by paint area. S-class sedan — 15–20% more than E-class, X7 — 25% more than X5.
Color. Black and dark colors ALWAYS need at least 2-stage polish. CSU Base on a black car is a compromise we usually argue against.
EXOv5 topcoat. Gtechniq's hydrophobic top layer adding water-bead effect. Without it CSU works structurally; with it shines brighter in sun. +12,000–22,000 ₽.
Glass and wheels. Gtechniq G1 ClearVision on glass — +12,000–18,000 ₽; C5 wheel protection — +18,000–28,000 ₽ per set.
Timing
CSU Premium on a sedan — 4–5 working days. CSU has long cure (24h after application, then 7 days to full polymerization). No washing for 14 days, no rain exposure for the first 24 hours.
FAQ
How does CSU differ from Ceramic Pro 9H by feel?
Right after install — almost nothing visually. After 2–3 years the gap appears: CSU keeps shine, Ceramic Pro starts losing hydrophobicity. After 5 years CSU looks fresh, Ceramic Pro needs refresh.
What does "certified installers only" mean?
Gtechniq sells CSU only to studios that completed UK training and hold an active certificate. Each CSU package has a batch number tied to a specific studio. Process violations void the warranty.
Can it go over PPF?
Yes and often does on premium cars: PPF against chips, CSU adds chemical protection and shine. Cost is standard — CSU is applied the same way over film as over paint.
What's the maintenance after CSU?
Every 6 months — pH-neutral wash (Gtechniq W4 recommended) and EXOv5 topcoat refresh as needed. Certified studio handles this under warranty for 5,000–10,000 ₽ per year.
