Vehicles after change point in 1982 Sealing Preparations - Underside of car must be clean and dry. - If applicable, damaged PVC on underside including wheel housings and side panels must be repaired and treated with Tectyl. The thickness of undercoating should not exceed 250 µm (0.25 mm / 0.010"). - Check car for paint finish damage and damage from flying stones and, if applicable, repair after consulting the customer. - Sealing compounds and the car itself should have room temperature (approx. 20° C/ 68° F). - Check spray pattern of guns and nozzles. - When drilling holes, dip the stepped drill bit in sealing compound to trap burrs. - Remove dripping sealing compound. - Insert plugs dipped in Tectyl in all drilled holes after finishing sealing. - Spray engine sealing compound on engine and engine compartment to cover completely. - When repairing body parts damaged in an accident or replacing the car body, body cavity sealing must be carried out immediately after painting and before installation of attachments, equipment, trim et.. If repair welding seams and joints are only accessible from one side, the side which produces a cavity has to be treated with wax. The same is applicable for the rear side panels, above the wheel housings up to the roof joint, as well as doors especially in the upper corner areas. Body cavity sealing performed after body repairs must be confirmed on the annual inspection sheets (Owner's Manual)! | |
