Panel & Rivet Bonding Standard Operating Procedure (SOP)
Use SEM's five step standard operating procedure (SOP) for flawless panel and rivet bonding repairs.
1. REMOVE PART
Remove spot welds with spot weld cutter. Remove rivets by drilling or grinding. Remove damaged panel and straighten bent flanges with a hammer and dolly.
2. DRY FIT
Dry fit all panels to ensure proper alignment. Drill holes for replacement rivets or mark locations of self-piercing rivets.
3. PREP & GRIND
Clean with SEM Solve or XXX Universal Surface Cleaner. Grind mating flanges with a 36 grit grinding disc at low speed for aggressive grind mark. Remove any adhesive or protective coatings.
NOTE: If rivet bonding, manufacturers may recommend leaving OEM e-coat on the surface of the new panel. If so, scuff with a red scuff pad.
4. APPLY ADHESIVE
Apply 3/8" - 1/2" bead of Dual-Mix™ Multi-Purpose Panel Adhesive or Dual-Mix Weld-Bond Adhesive to both surfaces. Use enough material to completely fill the joint when parts are clamped. Tool with a spreader or acid brush. Cover all exposed bare metal.
NOTE: For smaller parts use Dual-Mix Door Skin & SMC Adhesive.
5. (OPTION 1) PANEL BONDING
Clamp panel into place. Do not over clamp. Wipe away excess material.
TECH TIP: For maximum bond strength, surfaces must be mated during adhesive's working time.
(OPTION 2) RIVET BONDING
Clamp panel into place. Install rivet's per manufacturer's recommendations during adhesive's working time. Remove clamps after rivets have been installed. Wipe away excess material.
