Gtechniq Ceramic Coating: Brand Guide

A British brand built on surface science

Gtechniq was founded in the UK and remains a British brand at heart, which feels fitting given how hard British weather punishes paintwork. The company formulates its own coatings rather than rebadging generic products, and its professional range has been used on everything from daily drivers to concours winners.

That professional focus is the brand's signature. While many coating brands chase the consumer market, Gtechniq's flagship products were designed for trained applicators in controlled conditions, which is exactly why the name carries weight with people who coat cars for a living.

The key Gtechniq coating lines, explained

Crystal Serum, and its flagship sibling Crystal Serum Ultra, is the professional-only coating the brand is famous for. Supplied to approved detailers rather than sold at retail, it is known for exceptional hardness and chemical resistance. It is typically finished with EXO, Gtechniq's hydrophobic top coat, for dramatic water beading.

The consumer side includes C1 Crystal Lacquer, a genuine coating for careful DIY users, and C2 Liquid Crystal, a popular spray sealant for maintenance. C5 Wheel Armour and G1 ClearVision cover wheels and glass. The professional and consumer tiers are deliberately separate: different chemistry, different expectations.

• Crystal Serum and Ultra: professional-only flagship coating with extreme hardness
• EXO: hydrophobic top coat, usually applied over Crystal Serum
• C1 Crystal Lacquer: consumer-grade coating for enthusiast application
• C2 Liquid Crystal: spray sealant for topping up protection
• C5 Wheel Armour and G1 ClearVision: dedicated wheel and glass coatings

Professional-only versus consumer coatings

Professional-only coatings such as Crystal Serum Ultra are restricted to trained, approved detailers for good reason. They cure quickly, demand precise levelling and punish poor preparation, but offer hardness and longevity consumer products cannot match. A pro coating without the pro is not an option.

Consumer coatings and sprays have their place: forgiving, affordable and genuinely effective as maintenance. But if you want the flagship result, the hardest and longest-lasting finish a brand offers, it comes through a professional detailer with the training, environment and paint-correction skills to do it justice.

Getting a professional coating in Colchester

A professional-grade coating service follows the same discipline whatever the brand on the bottle: full decontamination, machine polishing, panel wipe, careful application and proper curing. The brand matters less than the preparation: a perfectly prepped car with a mid-tier coating beats a rushed flagship job.
