Seam SealersSealers are intended to

Seam SealersSealers are intended to prevent water and dust from entering the vehicle and also are anti-corrosion barriers. Sealersare applied to such areas as rear compartment lid hem flanges, wheelhouse, quarter outer, floor, cowl, roof, and variousother panel to panel attaching points. The originally sealed joints are obvious and any damage to these sealed locationsshould be corrected by resealing. Attaching points of new replacement panels should be resealed. Replacement lidsand doors will also require sealing in the hem flange areas.Flanged joints, overlap joints, and seams should be sealed using a quality sealer of medium-bodied consistency. Thesealer used must retain its flexible characteristics after curing and be paintable.Open joints which require bridging of the sealer in order to close a gap should be sealed using a heavy-bodied caulkingmaterial. Follow the label directions for the material selected.Color application may be required in order to restore repaired areas such as hood, fenders, doors, quarters, lid, roof,engine compartment, underbody, and inner panels to original appearance. When this is necessary, conventional refinishingpreparation, undercoat buildup, and color application techniques should be followed.Deadener materials, spray-on type, are used on various metal panels in order to provide corrosion resistance and jointsealing. They control the general noise level inside the passenger area of the vehicle. When deadeners are disturbedbecause of damage, are removed during repair operations, or a new replacement panel is installed, the deadener materialmust be replaced by a service equivalent material. The application pattern and location of deadener materials can bedetermined by observing the original production installation.Cleaning of the interior and underbody panel surfaces is necessary when original galvanized or other anti-corrosionmaterials have been burned off during welding or heating operations. Removal of the residue from burning will requireadditional care in such areas as interior surfaces of box-type construction and when configurations of the metal panelslimit access to interior surfaces.
