Gtechniq
Quick answer: Gtechniq is a car care brand known for ceramic coatings and aftercare products for paint, glass, wheels and interiors, supplied for DIY use and via accredited professional installers.
What it means
Gtechniq develops surface-protection products that bond to the clear coat and other substrates to improve gloss, chemical resistance and water behaviour. The range spans long-lasting ceramic coatings, top-coats/toppers, glass and trim coatings, shampoos and maintenance products. Some items are installer-only with warranty terms that depend on preparation and correct application.
Why it matters
Gtechniq is a system rather than a single product. The range spans durable ceramic coatings, shorter-term toppers and the maintenance chemistry meant to be used alongside them, so what a customer has had applied depends entirely on which part of the range was specified.
Installation is the other half of it. Accredited application and defined prep standards are how consistent results are achieved and how warranties are validated, which means the paperwork attaches to the process as much as to the bottle. Aftercare follows the same logic, with compatible wash products and toppers maintaining water behaviour and gloss over time. The limits are the same as for any coating: resistance to chemicals and fine marring improves, and nothing about it makes paint scratch-proof.
Where Gtechniq turns up
Detailers' service menus, accredited installer pages, dealership upgrade lists and retail shelves for maintenance products all carry the name. Customers usually arrive having read about a specific product in the range rather than the range itself, and quotes record the system and layer count applied. Inspection notes refer to it when establishing what is already on a car before anything further is proposed.
Context
Gtechniq comes up more in our workshop pre-appointment conversations than almost any other brand name; by the time a customer arrives having read about Crystal Serum, the useful part of the discussion is usually about prep standard and aftercare rather than the coating name itself.
Common mistakes
- Assuming any "ceramic" from the brand gives the same durability - installer-only coatings and retail toppers are different.
- Thinking a coating is scratch-proof - it improves resistance but cannot stop all marring or chips.
- Skipping preparation and panel wipe, which undermines bonding and longevity.
- Using harsh cleaners routinely that strip toppers and dull behaviour.
- Ignoring cure and aftercare guidance required for warranty terms.
