Standard Operating Procedure
Our Panel Bonding SOP provides best practices for pre-fitting, cutting, panel prep and installation when following OEM recommendations for panel bonding adhesives.
Using a grade 80 abrasive belt, remove remaining weld nugget material from host panel. Prep remaining mating flanges on host panel with a coarse Scotch-Brite™ Belt to remove all adhesive, corrosion and coatings.
Remove E-coat from replacement panel mating flange areas using Scotch-Brite™ Belt or Clean and Strip disc.
Clean host panel and replacement panel mating flange areas with a VOC compliant surface cleaner.
Dry fit replacement panel and complete any necessary metal straightening at flanges areas. Remove panel in preparation for adhesive application.
Use Scotch-Brite™ Belt to prepare metal surfaces. Clean and apply weld-thru primer to all areas requiring MIG welding.
TIP: Do not use Weld-Thru Primer in adhesive bonding areas.
If vehicle construction necessitates, apply NVH material or foams at original locations as required.
Apply adhesive to mating flange areas on host panel and replacement panel, covering all bare metal areas. Apply an additional bead of adhesive at mating flange areas to ensure proper bond line thickness.
Install replacement panel to host panel. Clamp in place and make required welds on rear vertical seams, cosmetic joints, or where otherwise recommended by the directions for use, or the OE manufacturer. Follow recommended adhesive clamp times.
Tool excess adhesive squeeze-out from repair area prior to curing to seal the repair.
Note: Grinding to remove excess adhesive can expose bare metal, causing corrosion.
Apply foams at original locations as required.
