IMPORTANT:

Do not grip bonding surface.
It is not the time of the pressure, but rather the level of pressure (approx. 10... 15 N/cm² ) that is decisive.
Separation of seal after pressing destroys the adhesive layer.

NOTE: After being pressed on gently, seal can be pulled off again up to 3 times. Do not dirty bonding surface.

Suspend seal (1) with open lip pointing inwards over door. Pull protection of positioning aid (liner) off seal in sections.

Stick on seal (1) as follows:

Position seal with color coding on door window frame at front top.
