Preparing Bonding Surfaces
WARNING: This page is about a different variant/trim than selected.
Initial cleaning
Remove sticky, solid layers such as dirt, rust and old adhesive.
Cleaning
Then clean the bonding flange areas using a lint-free cloth soaked in isopropanol until there are no more residues on the cloth.
Leave cleaned surfaces to dry off for 15 minutes; the bonding surfaces must be completely dry.
