Information 

Separating body parts

• In the case of bonded panel joints with a hardened bonded layer on the outer panel, apply a generous amount of heat to heat up the outer panel in the area of the spotwelds. →  Diagram Of Body Bonding Points And Sealing Elements 
• After removing the loosened body part, old adhesive must be removed and any uneven spots sanded down. The flange area must then be pre-treated for bonding. For the procedure see: Information on the use of structural adhesive in vehicle manufacturing →  Information On The Use Of Structural Adhesives In Vehicle Construction
