Review: Gutes dauerelastisches Dichtband - Habe das Band zum Eindichten einer Dachluke, sowie mehrerer Lüftungsgitter am Wohnwagen benutzt. Lässt sich sehr einfach und gut verarbeiten. Es ist alles dicht. Das Produkt bleibt elastisch und härtet nicht aus! Damit ist es perfekt geeignet um vibrierende Bauteile oder welche mit starker Wärme- Kälte-Ausdehnung abzudichten.
Review: Bon produit - Butyle de bonne qualité. Utilisation camping-car.
