With the sealing compound used by our company, it is unfortunately unavoidable that it continues to 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 a purely visual impairment. The excess sealing compound can be removed with a blunt object, e.g. plastic wedge, and the dirt residues can be cleaned with a cleaner, e.g. isopropanol.
