21CARS® Windscreen Sealant – Clear Vision in Rain & Increased Road Safety

21CARS® Windscreen Sealant is the ideal solution for anyone looking for a car windscreen sealant with a lotus effect. Thanks to its innovative nano-coating, it creates a reliable beading effect, causing rain, dirt, and even oily residue to effortlessly roll off the windscreen. Even at speeds as low as 50 km/h, the airflow ensures that droplets simply disappear – the windscreen, side windows, and rear window stay cleaner for longer, and the wiper blades are needed far less often. This means improved visibility, clear windows, and greater road safety. The glass sealant is available either individually in a 50 ml bottle or in a practical set with glass cleaner and wipes.

21CARS® Windscreen Sealant 50 ml

The 21CARS® windshield sealant ensures clear visibility in all weather conditions thanks to its water-repellent effect. The innovative, hydrophobic protective layer causes rain to simply bead off at speeds as low as 50 km/h – without the need for constant windshield wiper use. Additionally, the sealant prevents dirt, dust, and bird droppings from adhering stubbornly to the glass surface.

Application is incredibly easy: spray on, let it work briefly, and then polish with a microfiber cloth. The result is a transparent, streak-free protective layer that reliably protects your windows for weeks.

Advantages of windshield sealing

✔ Clear visibility in rain due to strong beading properties of aqueous and oily liquids
✔ Fewer deposits of insects, dust or bird droppings on all glass surfaces
✔ Makes cleaning easier – dirt adheres less strongly, a quick glass cleaning is sufficient.
✔ Long-term protection thanks to robust nano-sealing
✔ Reduces the use of windshield wipers and prevents streaking

Whether in everyday life or in professional vehicle preparation – the 21CARS® solution is among the best window sealants in the field of car care.

Anwendungsempfehlung:

The Application is particularly easy:

  1. Cleaning: Thoroughly clean the windows with glass cleaner and dry them.
  2. Application: Spray the sealant evenly onto the glass surfaces.
  3. Polishing: Leave on for 5-10 seconds, then polish streak-free with a microfiber cloth and coat the windows.
  4. Repeat: For maximum beading effect, repeat the process after approximately 20 minutes.
  5. After application, do not expose the car windows to rain for at least 12 hours to allow the coating to harden.

This creates a transparent, long-lasting coating that ensures better visibility in all weather conditions.
