Unfortunately, it is unavoidable that the sealant used by our company will swell slightly over time. However, this has no influence whatsoever on the tightness of the vehicle and therefore does not constitute a complaint under the warranty, but is purely a visual impairment. The excess sealant can be removed with a blunt object, e.g. a plastic wedge, and the dirt residue cleaned with a cleaner, e.g. isopropanol.
