3.1 Preparation of the surface on the vehicle (series status)

• Establish a level bonding surface (e.g. grinding). Do not remove the series primer entirely.
• Do not grind/sand bonding surfaces. 
• If necessary, pre-clean bonding surfaces with cavity sealing wax remover.

  Clean bonding surfaces with cleaning agent R1.

• Allow cleaned surfaces to dry for approx. 5 minutes.

Bonding surfaces must be completely dry.
