In principle replacement parts required for this repair can be replaced completely. Ensure that the standard joining and bonding connections are observed or are coordinated with the responsible Daimler departments in individual cases. On cut panels also ensure that the joints to the present paneling are accessible for later cavity preservation and that the minimum distance between foam-protected areas and connection points is approx. 100 mm.
