Anti-Corrosion Treatment and Repair Emblems Decals Paint - part 3
Sealers are intended to prevent water and dust from enteringthe vehicle and also are anti-corrosion barriers. Sealers areapplied to such areas as rear compartment lid hem flanges,wheelhouse, quarter outer, floor, cowl, roof, and various otherpanel to panel attaching points. The originally sealed joints areobvious and any damage to these sealed locations should becorrected by resealing. Attaching points of new replacement panelsshould be resealed. Replacement lids and doors will also requiresealing in the hem flange areas.
Flanged joints, overlap joints, and seams should be sealedusing a quality sealer of medium-bodied consistency. The sealerused must retain its flexible characteristics after curing and bepaintable.
Open joints which require bridging of the sealer in order toclose a gap should be sealed using a heavy-bodied caulkingmaterial. Follow the label directions for the materialselected.
Color application may be required in order to restorerepaired areas such as hood, fenders, doors, quarters, lid, roof,engine compartment, underbody, and inner panels to originalappearance. When this is necessary, conventional refinishingpreparation, undercoat buildup, and color application techniquesshould be followed.
Deadener materials, spray-on type, are used on various metalpanels in order to provide corrosion resistance and joint sealing.They control the general noise level inside the passenger area ofthe vehicle. When deadeners are disturbed because of damage, areremoved during repair operations, or a new replacement panel isinstalled, the deadener material must be replaced by a serviceequivalent material. The application pattern and location ofdeadener materials can be determined by observing the originalproduction installation.
Cleaning of the interior and underbody panel surfaces isnecessary when original galvanized or other anti-corrosionmaterials have been burned off during welding or heatingoperations. Removal of the residue from burning will requireadditional care in such areas as interior surfaces of box-typeconstruction and when configurations of the metal panels limitaccess to interior surfaces.
