16. Install clamps and screws to locations determined during the dry fit process.
17. Remove all squeeze out of adhesive, prior to curing.
NOTE: Structural adhesive manufacturers will vary on time allowed for completion of STRSW in weld
bond zones. Check and follow adhesive manufacturer recommendations.
18. Apply STRSW to weld bond area immediately.
19. Once fully cured, remove clamps and screws. When fully cured, expect adhesive to remain a little tacky, as this
is a normal characteristic of the adhesive.
20. Complete STRSW and / or GMAW (plug / puddle ) welds.
21. Finish / Dress the welds as necessary. If screws were necessary bevel the screw holes. Prepare the joint and
screw holes by grinding the area with 50 grit grinding disc. Get in seams as best as possible without thinning
the metal.
22. Remove any excess cured adhesive with a grinder or abrasive disc. All adhesive must be removed from the
cosmetic repair area to ensure proper adhesion of repair and refinish materials.
23. Apply fiber-reinforced waterproof body filler to screw holes and joint. Complete the repair using conventional
body filler, and block sanding.
24. Apply an epoxy or anti-corrosion primer. When cured, lightly scuff and then apply seam sealer as necessary.
25. Prime and paint per paint manufacturer recommendations.
26. Apply inner panel corrosion inhibiting materials (Mopar Cavity Wax part #68042970AA, or equivalent).
Metal Fatigue/Stress Crack
Overview: On rare occasions you may encounter metal fatigue, also referred to as stress cracks. This will appear
as a crack starting at an edge and trailing away. Follow these steps for a proper repair:
1. Locate the trailing end of the crack and drill a 3 mm. (1/8 in.) hole at the very point at which it stops. This is
referred to as "Stop Drilling".
2. Remove all contaminants and coatings including primer, paint and anti-corrosion, from the repair area. Surface
should be clean and shiny (if pewter in color then anti-corrosion has not been removed).
3. Identify the type of metal to be welded and the recommended welding process for that metal as found in
Standardized Steel Identification
(Refer to 31 - Collision Information/Specifications/Standardized Steel Identifica-
tion)).
4. Stitch weld the seam/crack closed using the recommended welding process and in accordance with the
welding guidelines as found in Weld/Weld Bonding
(Refer to 31 - Collision Information/Standard Procedure/
Welding and Weld Bonding).
5. Dress the welds as necessary. Careful not to thin the base metal.
6. Depending on the location and visibility of the repair surface refinishing will vary from body filler, finishing and
painting to simply applying an epoxy or anticorrosion primer and rubberized undercoating, Mopar part
#05093417AA or equivalent.
7. Apply inner panel corrosion inhibiting materials (Mopar Cavity Wax part #68042970AA , or equivalent).
