19. Weld the butt­joint with GMAW (Gas Metal Arc Welding), if a belt cut was used. Clean and dress welds accordingly.
20. Apply fiber­reinforced waterproof body filler to the section seam, as necessary. When cured sand and apply con­
ventional body filler and block sand.
21. Apply an epoxy or anti­corrosion primer. When cured, lightly scuff.
22. Seam seal the entire door. Duplicate the factory seam sealer. Apply a discrete bead around the rest of the door to
seal and protect, maintaining the original appearance.
23. Prime and paint per paint manufacturers recommendations.
24. Apply inner panel corrosion inhibiting materials (Mopar Cavity Wax part #68042970AA , or equivalent).
Side Aperture / Quarter Panel
Overview: Chrysler's recommended repair procedure for body side aperture / quarter panel replacement include butt
joints using backer panels with structural adhesive at the sectioning joint, or a welded backer panel with a welded butt
joint using GMAW (Gas Metal Arc Welding). Resistance spot welding with structural adhesive, referred to as weld bond­
ing, should be used at all pinch welds and may be used at the drain trough and tail panel areas as well. With the
exception of the sectioning joint, the rule to follow is "Re­assemble as it was built from the OEM". For further information
on Weld / Weld Bonding,(Refer to Collision Information ­ Standard Procedure). GMAW (plug or puddle) welds may be
used in place of STRSW (Squeeze Type Resistance Spot Welding) only in areas that specifically use spot welds and in
areas that access limitations will not allow STRSW. GMAW cannot be used in the weld bonding process. Never weld
with GMAW within 25mm. (1in.) of any area where structural adhesive is used. The weld "heat zone" will destroy the
properties of the adhesive.
Vehicle design will determine if the sectioning location is to be in the pillar or the roof line area. Reference the vehicle
specific Body Repair Manual to verify if any specific locations or warnings apply to body side aperture / quarter panel
sectioning locations. Reference Sectioning Procedures, (Refer to Collision Information ­ Standard Procedure).
