The automotive sealant repels water and grime while boosting showroom gloss. It keeps maintenance time down and helps paintwork look newer for longer. Is long-lasting, scientifically tested protection worth the effort with Gtechniq C2 Ceramic Sealant?

⚡ At a Glance
  • Protection Performance: Strong hydrophobic action produces pronounced water beading and reduces surface soiling
  • Best for: Owners who want durable water repellence and a high-gloss finish with DIY application
  • Not ideal for: Users seeking an instant spray detailer rather than a layered sealant

Hydrophobic sealant designed for paintwork, trim, tyres and windows. Lab and real-world tests report high swirl resistance and UV protection.


Long-lasting water repellence – thanks to molecular nanotechnology

Engineered nanoparticles bond at a molecular level to form a hydrophobic layer that encourages water to bead and run off. The formulation is based on Gtechniq's molecular nanotechnology heritage and extensive testing.

Strong beading keeps surfaces dryer and reduces the need for frequent washes, making maintenance quicker and less abrasive to paintwork.

Simple DIY application – with a wipe-on, panel-by-panel routine

Application requires a clean, dry surface and a microfibre buff cloth such as the Gtechniq MF1 ZeroR; treat one panel at a time and avoid direct sunlight during application.

Suitable for enthusiasts with basic kit, as no specialist polishing machine is needed and users report no buffing required for good results.

Improved gloss and durability – with layerable sealant chemistry

Layering the formula increases surface depth and gloss while the coating's composition has been tested in lab and real-world conditions for UV and swirl resistance.

Multiple thin layers build a resilient shine that helps guard against light swirl marks and UV fade, extending paintwork appearance between more involved detailing.
