Soft99 Glaco Blave plastic sealant 70ml

Seal glass and plastic in one step with Soft99 Glaco Blave

What makes Glaco Blave special? Soft99 Glaco Blave is the only sealant in the Glaco series that works on both glass and plastic—from helmet visors and headlights to safety goggles. The hydrophobic coating repels water instantly, with no drying time.

The Soft99 Glaco Blave fills a gap that classic glass sealants leave open: the protection of plastic surfaces. While products like Ultra Glaco are designed exclusively for vehicle glass, Glaco Blave seals both mineral glass and polycarbonate, Plexiglas, and other plastics—all with a single formula. For the user, this means in everyday life: helmet visors, headlight covers, safety goggles, taillights, and even windshields can be treated with the same product. The silicone resin-alcohol formula creates a hydrophobic layer that reliably repels rainwater and significantly reduces the adhesion of insect residues, road grime, and spray. With 70 ml content and its compact format, Glaco Blave is also an ideal companion for on the go—whether in a motorcycle tank bag, tool bag, or glove compartment.

• Dual material compatibility: glass and plastic in one product. Glaco Blave is specially formulated for surfaces that other glass sealants cannot tolerate. Polycarbonate helmet visors, acrylic glass headlights, and plastic safety goggles are sealed just as reliably as conventional vehicle glass. In practice, this means: one product for all transparent surfaces on the vehicle and equipment.
• Instant effect without drying time. Unlike classic glass sealants, which need 10 to 60 minutes to cure, Glaco Blave works immediately after application and wiping off. This avoids long waiting times and makes the product perfect for quick treatment between two rides or just before a rain ride.
• Hydrophobic protection for motorcyclists and spectacle wearers. On helmet visors, the coating prevents the typical film of water that severely restricts visibility in the rain. Insect residues and road dirt adhere less and are much easier to remove—a noticeable safety gain for motorcyclists in bad weather.

Practical tip from Detailing1: In practice, we recommend reapplying Glaco Blave to helmet visors after every thorough cleaning—the beading effect on plastic typically lasts four to six weeks. For vehicle glass surfaces that you want to seal for longer, you're better off using Ultra Glaco or Glaco Roll On Large—they are optimized for glass and last significantly longer there.

Silicone resin-alcohol formula — why Glaco Blave works on plastic

Most glass sealants use fluoropolymers or pure silicone oils, which adhere excellently to mineral glass but can attack or cloud plastic surfaces. The Soft99 Glaco Blave uses a special silicone resin-alcohol combination that adheres to both glass and polycarbonate and acrylic glass without damaging the material. The alcohol content in the formula serves as a carrier medium: it evaporates completely after application, leaving only the thin silicone resin layer on the surface. This layer reduces the surface tension of the treated material, so water droplets contract into small spheres and cannot form a closed film. The effect is just as visible on plastic as on glass—raindrops bead off instead of spreading as a film of water over the entire surface. An important difference to pure glass sealants: the silicone resin layer is less hard and resistant than the fluoropolymer coating of Ultra Glaco. On glass, it therefore only lasts a few weeks compared to months. On plastic, however, this is irrelevant, because harder coatings cannot be used there anyway without damaging the material.

Applying Glaco Blave correctly — on helmet visors, headlights and glass

The application of Glaco Blave differs slightly depending on the surface, but always follows the same basic principle. First, clean the surface thoroughly—for vehicle glass, a normal glass cleaner is sufficient; for helmet visors and plastic, it's best to use lukewarm water with a drop of mild dish soap. Important: Do not use aggressive cleaners or abrasives on plastic, as these can scratch the surface. After drying, apply Glaco Blave with the integrated felt applicator. Gently squeeze the bottle until the felt is damp, and spread the liquid in even, overlapping strokes. Unlike Ultra Glaco, you don't have to wait for a white haze to appear—wipe the treated surface immediately with the included microfiber cloth. The result is immediately visible: the surface feels smoother and water droplets bead off immediately on the next contact. For helmet visors, we recommend treating only the outside—the inside can fog up due to breath moisture if the silicone resin layer is applied. For headlights and taillights, do not let the sealant run into the seals.

Areas of application and results — where Glaco Blave excels

The Glaco Blave is most beneficial where conventional glass sealants cannot be used. The primary area of application is helmet visors: motorcyclists know the problem—in the rain, a film of water forms on the visor, severely restricting visibility. The Glaco Blave prevents this film and allows individual drops to form, which are carried away by the wind at moderate speeds. The effect is particularly noticeable on motorcycles because the wind directly hits the visor. A second important area of application: polycarbonate headlights and taillights. The hydrophobic layer significantly reduces the adhesion of road grime and spray—the lights remain clearer longer during night driving and light output remains higher. Safety glasses for DIY enthusiasts, sports glasses, and even Plexiglas shower walls also benefit from the sealant. The realistic durability varies depending on the surface: on plastic, expect four to six weeks; on glass, three to four weeks. On heavily used helmet visors that are cleaned regularly, the effect may diminish after two to three weeks.

Glaco Blave vs. Ultra Glaco — why you need a separate product for plastic

The question often arises: Can't you just use Ultra Glaco on plastic? The short answer: No. Fluoropolymer-based sealants like Ultra Glaco are optimized for mineral glass and can attack polycarbonate and acrylic glass—in the worst case, milky hazing or fine cracks may appear on the plastic surface. The Glaco Blave is explicitly formulated for these materials and does not damage them. In direct comparison: Ultra Glaco provides a significantly stronger and longer-lasting beading effect on glass (up to 12 months vs. a few weeks). On plastic, however, Glaco Blave is without alternative in the Glaco family—no other product in the series is approved for polycarbonate. If you want a complete glass protection package for your vehicle, combine Ultra Glaco or Glaco Roll On Large for the windshield with Glaco Blave for headlights, taillights, and other plastic covers.

Who is Glaco Blave ideal for — purchase recommendation and target group

The Soft99 Glaco Blave is the first choice for motorcyclists who want to treat their helmet visor to be water-repellent—no other product in the Glaco series is suitable for this. At the same time, car drivers whose vehicles have plastic headlights or taillights benefit: the hydrophobic layer keeps the lights clear longer during night driving and in bad weather. Glaco Blave is also a practical solution for spectacle wearers with sports glasses, safety glasses, or ski masks made of polycarbonate. The compact 70 ml format fits in any tank bag and tool bag. For complete vehicle care, we recommend the combination: Ultra Glaco for the windshield, Glaco Mirror Coat Zero for the exterior mirrors, and Glaco Blave for all plastic surfaces. The only limitation: if you are looking for a long-lasting sealant for pure glass surfaces, you are better off with Ultra Glaco or Glaco DX—Glaco Blave is not designed for long-term use on glass, but is optimized for plastic surfaces.
