Soft99 Glaco Q window sealant 75ml

Cleaning and Sealing in One Step — Soft99 Glaco Q as a 2-in-1 Windscreen Treatment

What makes Glaco Q special? Soft99 Glaco Q combines glass cleaner and windscreen sealant in a single product: The integrated compound cleaner removes dirt, oil film, and old sealant residues, while the hydrophobic coating is applied simultaneously — a completely treated windscreen in one go, effective from just 45 km/h.

The Soft99 Glaco Q is the most beginner-friendly product in the entire Glaco series — and also one of the smartest. The 2-in-1 formula combines a mild compound cleaner with a hydrophobic silicone coating in a single application. You don't need a separate glass cleaner beforehand, no extra step, and no experience with windscreen sealants. The integrated cleaner removes oil films, insect residues, wiper streaks, and old sealant residues, while you simultaneously apply the new coating. The ergonomic felt applicator on the bottle makes application intuitive: lightly squeeze the bottle, move it over the windscreen, done. The white product color shows you exactly which areas you have already treated. With 75 ml content, one bottle is enough for approximately seven complete windscreen treatments.

• 2-in-1 Formula: Glass cleaner and sealant in one step. Glaco Q saves you the usual two-step process of cleaning and sealing. The compound component abrades the glass surface, while the silicone component immediately builds up the hydrophobic protective layer. In practice, this means: one product, five minutes of work, finished sealant — ideal for beginners and those with little time.
• Beading effect from just 45 km/h — perfect for city traffic. Unlike many windscreen sealants that only become noticeable on the highway, Glaco Q works at low speeds. In city traffic, on country roads, and at moderate speeds, raindrops reliably roll off — a decisive advantage for commuters and everyday drivers.
• Ergonomic felt applicator for even application. The built-in felt applicator of Glaco Q is shaped to reach even the corners and edge areas of the windscreen. The white color of the product acts as a visual control: where white residues are visible, it has been treated — where not, a layer is still missing.

Practical tip from Detailing1: Glaco Q is excellent for getting started in the world of windscreen sealants. If you are trying a windscreen sealant for the first time and are unsure whether you need the separate cleaning step with the Glaco Glass Compound Roll On, Glaco Q is the perfect choice: you get both in one and can start immediately.

How the Glaco Q 2-in-1 Compound Formula Works

The Glaco Q combines two normally separate work steps in one product: The whitish liquid contains fine compound abrasive particles that mechanically remove impurities and surface residues during application, as well as hydrophobic silicone polymers that simultaneously adhere to the cleaned glass surface. This double mechanism works because the cleaning particles have a slightly abrasive effect — strong enough to remove oil films, insect residues, and old sealant layers, but mild enough not to damage the glass. The white color of the compound particles has a practical side effect: it shows you exactly where you have already worked. Once the white residues are evenly distributed, you know that the entire surface has been treated. Compared to the separate procedure with the Glaco Glass Compound Roll On as a cleaner and then the Ultra Glaco as a sealant, the cleaning performance of Glaco Q is slightly milder and the sealant layer a bit thinner — but a single work step accomplishes what would otherwise require two products and double the time.

Applying Glaco Q Correctly — Step-by-Step to the Perfect Windscreen Sealant

The application of Glaco Q is intentionally kept uncomplicated. First, ensure that the windscreen is dry and roughly free of loose dirt — perfect pre-cleaning is not necessary thanks to the integrated compound cleaner. Remove the protective cap from the applicator, hold the bottle at an angle against the windscreen, and press lightly to release the product. Guide the felt applicator in even circular motions over the entire windscreen — the applicator is shaped so that you can easily reach the corners and edge areas. You will feel the compound lightly abrading the surface — this is intended and indicates that the cleaning is working. Let the product act for five to ten minutes until the white residues dry. Then wipe with a slightly damp microfiber cloth and polish with a second, dry cloth. A common mistake: too little pressure during application. The compound needs moderate pressure to unfold its cleaning effect. If you just lightly wipe it, you will get weaker cleaning and thus a less durable sealant.

Beading Effect and Durability — Glaco Q in Everyday Use

The beading effect of Glaco Q starts at approximately 45 km/h — a value that makes the product particularly attractive for city traffic and country roads. In the rain, drops visibly roll off even at moderate speeds, and at highway speeds, they are literally blown away by the airflow. The durability of the sealant is a realistic six to eight weeks under normal driving conditions. Factors such as frequent wiper use, aggressive car washes, and strong UV radiation can shorten the lifespan. Compared to the Ultra Glaco with up to twelve months of durability, Glaco Q is shorter-lived — but also much faster to apply and easier to re-treat. If you want to extend the durability, you can refresh it after four weeks with the Glaco W-Jet — the spray sealant can be sprayed on in seconds and extends the protection by another four to six weeks, without you having to repeat the entire cleaning process.

Glaco Q vs. Glaco Roll On Large — 2-in-1 vs. Specialty Sealant

The Glaco Q and the Glaco Roll On Large appeal to different types of users. Glaco Q is the pragmatic solution: one product, one step, immediately ready. The Roll On Large is the specialist solution: stronger beading effect, longer durability of two to three months, but it requires a clean, prepared glass surface. Specifically: before the Roll On Large, you should ideally use the Glaco Glass Compound Roll On for basic cleaning. Glaco Q takes care of this cleaning step simultaneously. The beading effect of both products starts at 45 km/h, but with the Roll On Large, it is slightly more intense at the same speed due to the thicker sealant layer. For beginners, occasional users, and those with little time, Glaco Q is the better choice. Those willing to invest ten more minutes for significantly longer durability should opt for the Roll On Large — or for maximum longevity, directly for the Glaco DX or Ultra Glaco.

Who is Glaco Q ideal for — Purchase Recommendation and Application Area

The Soft99 Glaco Q is the best windscreen sealant for beginners and drivers looking for an uncomplicated all-in-one solution. You need no prior knowledge, no additional products, and no elaborate preparation. Glaco Q is particularly recommended for commuters and city drivers who benefit from the low activation speed from 45 km/h — many windscreen sealants only show their effect at significantly higher speeds. Glaco Q is also useful as a quick interim solution: if you notice that the beading effect of an older sealant is diminishing, you can clean and reseal simultaneously with Glaco Q. For the side windows, combine Glaco Q with the Glaco Blave — its felt applicator is specially shaped for smaller side windows. The exterior mirrors are best treated with the Glaco Mirror Coat Zero, which is specially formulated for mirror surfaces. The only limitation: those who want to treat heavily soiled windscreens with stubborn deposits should first use the Glaco Glass Compound Roll On — the pure compound cleaner has a stronger abrasive effect than the milder 2-in-1 formula of Glaco Q.
