Experience report

Practical impression

The manufacturer promotes its Glaco Roll On glass sealant as an “invisible wiper” from around 45–60 km/h, with significantly improved visibility. Independently of the formal test objective, we assess whether wiper use is practically eliminated and whether visibility in everyday driving actually improves.

‍

Application: Clean the windshield, apply in a cross pattern, allow to flash off for 5–10 min, wipe off – quick, self-explanatory, and tolerant of minor errors. Disposable gloves and fresh air are advisable (noticeable alcohol odor). In practice, it’s hard to do anything wrong.

Driving impression: Below ~50 km/h, droplets are visible and wiper intervals become noticeably longer. Between ~50–80 km/h, droplet movement is briefly perceptible but not disturbing; above >80 km/h the windshield appears very calm, and droplets are barely visible. Overall: less light scatter/glare and more relaxed driving.

Conclusion from a consumer perspective: convincing across the board, pronounced hydrophobic effect – highly recommended. Noticeable “invisible wiper” effect from ~50 km/h.Note: Contains propanol; ventilate during application and avoid skin contact. No child safety closure and visually appealing – store out of reach of children.Rundum überzeugend, ausgeprägte hydrophobe Wirkung – sehr empfehlenswert. Spürbarer „unsichtbarer Scheibenwischer“-Effekt ab ~50 km/h . Hinweis: Propanolhaltig; während der Anwendung lüften und Hautkontakt vermeiden. Ohne Kindersicherung und optisch ansprechend – außer Reichweite von Kindern lagern.
