1 ­ SECTION JOINT WITH BACKER PANEL
2 ­ WELD BONDING (AREAS WHERE ACCESSIBLE)
3 ­ BODY SIDE APERTURE
Preparation:
NOTE: Be certain vehicle is evenly supported at normal suspension points.
1. Restore structural dimensions as well as all related mating flanges.
2. Once sectioning locations have been established, cut original and replacement panels at the pre­determined loca­
tions. Remove spot welds within sectioned parameter.
NOTE: Be careful not to destroy any areas that may be able to be used as backer panels.
3. If panel is attached with adhesive, you may use heat, from a non­flame heat source, up to 204°C. (400F°). This will
aid in loosening the bond.
4. Use an air chisel with a flat bladed bit to remove original panel.
5. Using a hammer and dolly, restore any and all damage to mating surfaces.
6. Create backer panels to be used at butt joints. Refer to Backer Panel Joint
NOTE: It will be difficult to abrade the underside mating surface of the original panel, where backer panel is to
be used, however this is important step and should be done effectively.
7. Grind all mating surfaces with a 50 grit grinding disk. Remove all adhesive, sealers, paint, E­coating and corrosion
protective coatings from the area where the structural adhesive and welds will be applied. The metal should be
completely bare and shiny in appearance, if the metal appears pewter in color all of the galvanized coating has not
been removed.
8. Pre­ drill any GMAW plug / puddle weld holes that may be necessary, with a 8mm. (5/16in.) hole.
