Performance Products is proud to offer these body repair panels to help you repair your Mercedes and not 'break the bank.' They are made to not only cover the typical rust area but to extend beyond that area to insure a clean repair and allow enough overlapping metal to connect with the existing vehicle structure before welding. They are manufactured under the rigid guidelines of International ISO 9001 Standards in modern high-tech production plants. Most other manufacturers don't follow these quality standards guidelines or use old technology.
