Can Gtechniq Crystal Serum Ultra be applied over PPF?

Yes — and that is the most common UK stack: film first, then CSU plus EXOv5 on top of the film and on uncovered glass and wheels. For matt PPF wraps, confirm compatibility with your installer first; CSU is gloss-biased and not every matt film accepts it.

How do I verify a Gtechniq Accredited Detailer?

Gtechniq publishes the Accredited Detailer list on gtechniq.com. If the installer is not on that list, they cannot apply Crystal Serum Ultra or register its warranty — though they can still apply consumer-tier Gtechniq products such as CSL and EXOv5.

British ceramic coating brand and the most visible name in the UK detail scene. Crystal Serum Ultra is hand-applied only by Gtechniq Accredited Detailers — a deliberately small, vetted network. The accreditation matters more here than for any film brand.

The warranty, honestly

9-year warranty on Crystal Serum Ultra when applied by an accredited detailer. Self-applied versions exist (CSL, EXOv5) but the warranty drops accordingly.

How to verify an installer

Gtechniq publishes its Accredited Detailer list on gtechniq.com — if the installer isn't on it, they cannot apply Crystal Serum Ultra. Other Gtechniq products can be applied by anyone.

The Gtechniq read

What the brand actually is, what it makes, where it sits in the UK, and which buyer it suits.

Gtechniq is a British ceramic coatings brand founded by Rao Gangisetty and headquartered in Brackley, Northamptonshire, with manufacturing and R&D in the UK. It is a ceramic-only specialist — not a paint protection film maker — but sits in the GetPPF directory because most UK PPF studios offer a Gtechniq topcoat over film as part of a full-protection package. The brand is best known for Crystal Serum Ultra, a professional-only nanoparticle coating restricted to its Accredited Detailer network.

Films

The coatings, broken down

Gtechniq does not produce PPF; the range here is ceramic. Crystal Serum Ultra (CSU) is the flagship professional coating, applied exclusively by Accredited Detailers and carrying a 9-year durability claim. It uses a dual-layer structure with a 10H top layer and a softer 7H base layer, blending 7nm and 20nm nanoparticles for chemical and swirl resistance. Crystal Serum Light (CSL) is the consumer-accessible sibling, sold for DIY or non-accredited professional application with a shorter durability window. EXOv5 is the hydrophobic topper — a composite siloxane sacrificial layer designed to sit over CSU or CSL, boosting beading, sheeting and resistance to water spots. C2v3 is the entry-level spray sealant used for maintenance topping between deep details. For a PPF customer, the realistic stack in UK studios is film first, then CSU + EXOv5 on top of the film and on uncovered glass and wheels, sold as a combined ceramic-over-PPF package.

UK market position

Where Gtechniq sits in the UK

Gtechniq has the densest Accredited Detailer network of any ceramic brand in the UK, with studios in every major city and most market towns. Accreditation is gated — installers complete brand training, pass a paint-correction assessment and submit work for approval before they can apply CSU and register the warranty on Gtechniq's portal. The headline 9-year CSU guarantee is owner-transferable on resale and requires an annual inspection by an Accredited Detailer to remain valid. Typical UK retail for a CSU + EXOv5 application over a fully PPF-wrapped front end runs £600 to £1,200 on top of the film cost, depending on prep, correction hours and vehicle size. Maintenance details every 12 months sit around £250 to £450.

Who picks it

Who should pick Gtechniq

Gtechniq suits the UK buyer who has already chosen their PPF film and wants a British-made, network-verified ceramic layer on top — daily drivers, prestige saloons and EVs where hydrophobics, wash-mark resistance and easier maintenance matter more than raw thickness. It is the default ceramic for owners who value the transferable warranty on resale and the strict accreditation gate. For matte PPF wraps, confirm coating compatibility with your installer first — CSU is gloss-biased and not all matte films accept it.
