2.2.2 Procedure for previously bonded aluminium component
- Sand off adhesive residue and layers of paint.
- Clean bonding surfaces with cleaning agent R1.
- Allow cleaned surfaces to dry for approx. 5 minutes.
Bonding surfaces must be completely dry.
- Flame spray the surface:
- Go over the bonding surfaces slowly with the flame.
- Avoid flaming with the blue part of the flame.
