SONAX PROFILINE CeramicCoating "CC" Glass Ceramic Glass Sealant (12 Months) 50ml

Clear Vision in the Rain — Permanently Seal Windows with SONAX CeramicCoating CC Glass

What does a ceramic window sealant really achieve? SONAX CeramicCoating CC Glass creates an extremely hydrophobic glass surface, on which rain beads off at driving speed — for up to 12 months, with just one coat and without wiper chatter.

Anyone who drives a lot in the rain knows the problem: the windshield gets smeared, the wipers chatter, and in the dark, streaks make visibility even worse. A good window sealant solves precisely these problems — and SONAX CeramicCoating CC Glass goes a step further than classic nano-sealants. The ceramic formula creates a finely crystalline protective layer on the glass that doesn't just repel water and dirt, but smooths the surface structure so much that raindrops are literally carried away by the airstream at higher speeds. The result feels like an invisible, additional wiping system — but without moving parts, without wear, and with a durability of up to 12 months with a single application.

• Hydrophobic beading effect for safe visibility in wet conditions. The ceramic sealant creates a contact angle at which water droplets barely find any grip on the glass surface. From about 60–80 km/h, the airstream blows the droplets off the windshield without you having to turn on the wipers. In heavy rain on the highway, you'll notice the difference immediately — visibility remains clearer and driving becomes much more relaxed.
• Dirt-repellent surface all year round. Insect residues, bird droppings, tree sap, and road grime adhere much less to the sealed window. What usually only comes off with glass cleaner and pressure often dissolves on a CC Glass sealant during the next drive in the rain or during pre-washing. In winter, this has an additional advantage: frost and ice are noticeably easier to remove from the sealed surface.
• No wiper chatter — smooth wiper operation guaranteed. A problem that many glass sealants have: the wipers chatter and skip across the hydrophobic surface. With CC Glass, SONAX has fine-tuned the formula so that the wipers glide smoothly and quietly over the glass. So you can also use the sealant on the windshield without having to write off the wipers as a compromise.

Practical tip from Detailing1: Apply CC Glass at room temperature (20–25 °C) and allow at least four hours of curing time before the vehicle gets wet. For the first 24 hours, the sealed window should not be subjected to wipers — this ensures the ceramic layer reaches its full resistance. The ideal time is a dry Saturday in the garage or hall.

Ceramic Window Sealant — How CC Glass Works on Glass

Conventional glass sealants are often based on silicone oils or fluorine-containing compounds that form a water-repellent layer on the surface. SONAX CeramicCoating CC Glass, on the other hand, uses ceramic coating technology from the PROFILINE series — the same product family that includes CeramicCoating CC Evo for paint. The principle: the sealant forms an inorganic, finely crystalline layer that chemically bonds with the glass surface instead of just lying on it. This bond makes the sealant significantly more resistant to car washes, alkaline pre-cleaners, and windshield washer fluid than purely organic coatings.

A common misconception with glass sealants: many users expect the beading effect to work immediately and in every situation. The physics behind it is simpler than imagined — the hydrophobic layer ensures that water is no longer spread as a film on the window, but forms droplets. These droplets are only moved by the airstream, which is why the "invisible wiper" effect only really kicks in at around 60 km/h. In city traffic at 30 km/h, you will still need the wipers — but the sealant ensures that the wipers work cleaner and leave fewer streaks.

The pH resistance of CC Glass is in the range of pH 2 to 11. In practice, this means: normal car shampoos, windshield washer additives, and mild pre-cleaners are not a problem. Caution is advised with strongly alkaline cleaners with pH values above 11 — such products can remove the sealant more quickly. If you regularly work with snow foams or insect removers, pay attention to their pH value to maximize the durability of the sealant.

Another technical advantage of the ceramic formula over classic silicone sealants: it does not age due to UV radiation. Silicone-based glass sealants become brittle due to sunlight and lose their hydrophobic effect more quickly — especially on panoramic roofs and rear windows that get a lot of sun. The inorganic ceramic layer of CC Glass, on the other hand, is UV-stable and maintains its effect evenly on all glass surfaces, whether the windshield in the shade of the roof or the rear window in direct sunlight.

Applying Glass Sealant Correctly — Preparation and Step-by-Step Application

The best sealant is of little use if the preparation is not right. With CC Glass, glass preparation is the decisive factor for durability. Old sealant residues, oil films from windshield wiper additives, and fine limescale deposits form a separating layer that prevents the ceramic sealant from bonding properly with the glass. SONAX therefore recommends mechanical pre-treatment with PROFILINE GlassPolish glass polish and a felt pad on the polishing machine. The cerium oxide in the glass polish removes the finest layers and creates a perfectly clean, microscopically even surface.

After polishing, a thorough cleaning with a glass cleaner follows to remove all polish residues. Only on this completely grease and residue-free surface is CC Glass used. Apply enough product to a PROFILINE CoatingApplicator and spread it in a crosshatch pattern — first horizontally, then vertically — over an area of about 40 × 40 cm. Work the product in intensively instead of just wiping it thinly. This step significantly improves the bond with the glass. Repeat the process for each section of the window.

After application, the sealant needs 45–60 minutes to cure at 20–25 °C. Afterwards, polish off the residues with a fresh, clean microfiber cloth. Full curing takes 24 hours, although the vehicle may be carefully exposed to rain after 4 hours. However, you should not use the windshield wipers during the first 24 hours.

A note on the order for a complete reconditioning: the glass sealant always comes as the last step after the paint sealant. If you have overspray from a paint sealant on the windows beforehand, it is best to remove it with the glass polish in the same step. This prevents residues from the paint sealant from being trapped under the glass sealant. For side windows and the rear window, hand polishing with a microfiber cloth and GlassPolish is often sufficient — you mainly need the polishing machine for the windshield, which has the most wiper abrasion.

Beading Effect and Long-Term Effectiveness — When CC Glass Shows Its Full Strength

The glass sealant shows its strengths particularly when driving on country roads and highways. From 60–80 km/h, the airstream becomes strong enough to carry raindrops off the sealed windshield. On longer highway journeys in moderate rain, you can often do without wipers completely — a gain in comfort that you won't want to miss after the first rainy drive.

In heavier rain or in city traffic, the wipers work noticeably better on the sealed window: fewer streaks, cleaner wiping results, and no juddering. Even when driving at night, the sealant is noticeable because scattered light caused by a water film on the window is significantly reduced.

The durability of up to 12 months is realistic if the preparation was thorough and you avoid strongly alkaline cleaners during vehicle care. For vehicles without a garage that regularly go through car washes, the durability can drop to 6–9 months — still a very good value for a glass sealant. Consumption is 10–15 ml per vehicle (all windows), so the 50 ml bottle is sufficient for 3–4 complete applications.

What CC Glass cannot do: remove scratches from the glass or repair damaged windows. Deep wiper marks that make the glass appear dull must be treated with a glass polish before sealing — otherwise, you will seal the existing condition including the scratches. You should also not use CC Glass on plastic sunroof windows or Plexiglas covers — the product is formulated exclusively for real glass (mineral glass). For plastic surfaces, SONAX has its own product in its range, CeramicCoating CC Plastic+Rubber.

For vehicles that frequently cover long distances in the rain — such as company cars, commuter vehicles, or motorhomes — the safety gain from improved visibility is particularly high. The combination of less glare at night, faster water drainage, and reduced dirt adhesion noticeably reduces fatigue on long journeys in the rain. Drivers who spend a lot of time on unlit country roads particularly benefit from the fact that the scattered light from oncoming vehicles is significantly reduced by the lack of a water film on the window.

If you want to renew the sealant after its service life, a complete reconditioning is not necessary. A thorough cleaning with glass cleaner and subsequent reapplication is sufficient — mechanical polishing with GlassPolish is only absolutely necessary for the first application or for heavily soiled windows with old sealant residues.

Window Sealant Comparison — CC Glass vs. GYEON Quick View vs. Gtechniq G1

In the field of professional ceramic window sealants, there are several established products, each with its own strengths. SONAX CC Glass positions itself as a single-layer ceramic sealant with 12 months of durability — this is a strong value in comparison, as many competitors only achieve 6 months.

GYEON Q² Quick View is a popular alternative, particularly characterized by its uncomplicated application without a polishing machine. The durability is around 6 months, which is sufficient for many users. Anyone who wants to reseal their windows regularly and does not own a polishing machine will find a good entry point here.

Gtechniq G1 ClearVision uses a two-layer application and thus achieves durabilities of up to 2 years — however, the application is more complex and the product is significantly more expensive. For professional detailers who want to offer maximum durability, this is an interesting option.

SONAX CC Glass hits the sweet spot in between: single-layer application like Quick View, but with ceramic long-term durability close to G1 — and as part of a closed care system with coordinated glass polish, glass cleaner, and applicators from the PROFILINE series.

One aspect often overlooked in comparisons: wiper compatibility. Some very hydrophobic glass sealants create an impressive beading effect but at the same time cause the windshield wipers to chatter, skip, or leave streaks. CC Glass was explicitly formulated by SONAX to keep the wipers running smoothly — an advantage that is more noticeable in everyday life than a minimally stronger contact angle. Because a sealant that you can only use on side windows because the wipers on the windshield don't work only solves half the problem.

There are also interesting overlaps with spray sealants — such as the SONAX PROFILINE Ceramic SprayCoating or CarPRO Clarify PH2OBIC. These spray products can be applied much faster and are ideal for regular refreshing between ceramic applications. However, as a standalone glass sealant, they do not achieve the durability or layer thickness of a true ceramic sealant like CC Glass.

Buying Window Sealant — Who Benefits from CC Glass

SONAX CeramicCoating CC Glass is aimed at vehicle detailers and ambitious car enthusiasts who are looking for a professional glass sealant with maximum durability. If you already own a polishing machine and take your vehicle care seriously, CC Glass is the logical complement to paint sealing — because a sealed window significantly enhances the overall result of a reconditioning.

The combination works particularly well as a complete package: first seal the paint with CeramicCoating CC Evo or CC One, then treat the plastics with CC Plastic+Rubber, protect the headlights with CC HeadlightCoating, and finally seal all glass surfaces with CC Glass. This way, the entire vehicle is sealed in one system — with coordinated chemistry from a single source. For the customer of a professional reconditioning, this is a convincing overall package, and for the detailer, the complexity is reduced because preparation, curing times, and pH compatibility are coordinated within the PROFILINE system.

Priced at 50 ml for 3–4 applications per bottle, CC Glass is in the mid-range of professional glass sealants. Per vehicle, you can expect 10–15 ml, which keeps the cost per application manageable. For detailers who offer glass sealing as an additional service, this is an attractive calculation with high perceived value for the customer.

If you are trying CC Glass for the first time, you should start with the windshield — this is where the effect is most noticeable, and you immediately get a feel for the correct application and product quantity. Then follow with the side windows and finally the rear window. This way, you systematically work your way from the most critical to the least critical surface and will have developed the necessary routine by the time you reach the rear window to achieve an even and streak-free result on all vehicle windows.
