Body flange, preparing for window
installation
- Cut back remaining material on body flange with
scraper blade VAG1561/8 but do not remove
completely.
Note:
The remaining material acts as the adhesive base for
the new adhesive sealant which has to be applied.
Keep sealant free of dirt and grease.
CAUTION!
Do not prime adhesive surface, do not activate
and do not apply cleaning solution. Always keep
adhesive surfaces clean from dirt and grease.
Exception: If adhesion is not done immediately after
cutting back, the residual adhesive must be activated
with activator D 181 801 A1.
CAUTION!
Do not get activator on painted body parts
otherwise the paint will be damaged.
If the body flange was repaired or partially replaced,
clean the flange after painting and priming.
