GTechniq C2 Ceramic Sealant
GTechniq C2 Ceramic Sealant V4 is an advanced ceramic protection formula delivering extreme water and dirt repellency with extended 6-month durability. The latest formulation offers enhanced hydrophobicity, improved oil repellence, and superior self-cleaning properties.
Key Features
- Up to 6 Months Durability — Long-lasting ceramic protection reduces the frequency of reapplication compared to standard waxes, providing sustained protection throughout challenging seasons.
- Extreme Water Repellence — Advanced hydrophobic coating (4% increased water contact angle) causes water to bead instantly and sheet off completely, speeding drying and preventing water spotting.
- Enhanced Dirt Repellence — 7% boost in oil repellence repels grime, road film, and environmental contaminants, keeping paintwork cleaner between washes.
- Superior Self-Cleaning Properties — 13% improvement in surface-free energy creates active self-cleaning action - dirt and contamination slide off surfaces rather than bonding.
- Simple and Fast Application — Highly concentrated formula applies quickly with minimal product required, suitable for both hand application and use as a drying aid.
Description
Why Version 4 Represents a Significant Performance Upgrade
Ceramic Sealant V4 builds on years of development and user feedback to deliver measurable performance improvements over previous iterations. The laboratory testing data - 4% increase in water contact angle, 7% boost in oil repellence and 13% improvement in surface-free energy - represents real-world improvements that users experience every day. Better water beading means faster drying and fewer water spots. Enhanced oil repellency means dirt and road film don't bond as tenaciously to the paint. Improved surface-free energy means the self-cleaning mechanism works more effectively, with water carrying contamination away naturally.
Extreme Repellence Through Advanced Ceramic Chemistry
Modern ceramic sealants work fundamentally differently than traditional waxes. Where wax provides a physical barrier, ceramics form a molecular-level coating that bonds with the paint surface. This creates extreme repellence because the coating is chemically resistant to water and contaminants rather than merely physically waterproof. The advanced formulation in V4 refines this chemistry further, creating surface properties that repel not just water but also oily contaminants that standard ceramics struggle with.
Active Self-Cleaning for Maintained Appearance
The improvement in surface-free energy creates self-cleaning properties that work passively - without your involvement. When rain or cleaning water falls on a properly coated surface, it doesn't spread evenly across the paint. Instead, it beads up and runs off, carrying away dirt particles in the process. This means your vehicle stays cleaner longer even between washes. The coating essentially cleans itself through the natural action of water runoff.
Highly Concentrated for Efficiency
The note that "little goes a long way" reflects the product's concentration. You don't need to apply copious amounts to achieve excellent protection — light, even coverage is optimal. This concentration is economical, meaning a single bottle provides many applications. It also means faster application — you're not spreading thick layers that take extensive buffing.
Dual-Purpose as Drying Aid
The formula's flexibility as a drying aid demonstrates advanced formulation. Many ceramic products are one-purpose tools — apply, buff, done. C2 v4 works as a drying aid, applied to wet surfaces post-wash and dried with microfibre towels, simultaneously adding protection whilst drying the vehicle. This dual functionality appeals to users who want maximum efficiency from each product application.

Application Instructions
- Prepare clean, dry paintwork — Wash the vehicle thoroughly with a quality car shampoo (such as GTechniq GWash W1) and allow to dry completely. The surface must be clean and dry for optimal ceramic bonding and gloss results.
- Allow paint to cool — Do not apply in direct sunlight or on hot surfaces. Allow the vehicle to cool to ambient temperature after washing or sun exposure.
- Shake well before use — Mix C2 v4 thoroughly to ensure even consistency and optimal ceramic particle distribution.
- Wear gloves — Protect your hands by wearing gloves during application and buffing.
- Spray onto microfibre buff cloth — Spray the product onto a clean GTechniq MF1 ZeroR Microfibre Buff Cloth — do not spray directly onto the paint. Use a light application — the product is highly concentrated.
- Apply panel by panel — Working one panel at a time, wipe the sealant onto the paint using straight-line motions. Cover the entire panel surface evenly with a light, uniform coating.
- Buff with clean cloth immediately — Before the sealant begins to cure, use a second clean MF1 ZeroR Microfibre Buff Cloth to buff away the residue immediately. The goal is to remove all visible product residue whilst leaving a protective microscopic layer.
- Layer for enhanced protection — For increased gloss and protection longevity, apply a second or even third layer. Allow each layer to cure briefly (2–3 minutes) before applying the next layer. The layers bond to one another, creating enhanced protection.
- Alternative: use as drying aid — For rapid application or as a post-wash drying aid, spray C2 v4 onto wet surfaces panel by panel and immediately dry with a GTechniq MF4 Diamond Sandwich Microfibre Drying Towel. This applies protection whilst drying the vehicle in a single step.
- Allow full curing — Once all panels are complete, allow the vehicle to cure for 12–24 hours before washing or exposing to rain. This allows the ceramic layer to fully harden.

FAQs
How long does GTechniq C2 Ceramic Sealant v4 last?
The advanced formulation provides protection lasting up to 6 months depending on weather exposure, washing frequency, and environmental conditions. Vehicles in harsh UV climates or washed frequently may require reapplication every 3–4 months, whilst garaged vehicles can go 6 months between applications.
How many applications will one bottle provide?
The highly concentrated formula means one 30 mL bottle provides many applications — typically 10–15 full vehicle applications depending on panel coverage and application technique. Light, even coverage is optimal; heavy application wastes product without improving results.
Can I apply C2 v4 in layers for extra protection?
Yes, layering is recommended for enhanced protection and gloss. Apply one layer, allow 2–3 minutes curing time, then apply a second or third layer. The layers bond to each other, creating cumulative protection and gloss enhancement.
Can I use C2 v4 as a drying aid instead of hand-buffing it?
Yes, C2 v4 works excellently as a post-wash drying aid. Spray onto wet surfaces panel by panel and immediately dry with a GTechniq MF4 Diamond Sandwich Microfibre Drying Towel. This simultaneously applies protection and dries the vehicle, offering maximum efficiency and reduced application time.
