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 adhesive area.

Clean bonding surfaces on paint with adhesive cleaner (sourcing reference: BMW Parts Department).

Pull protective film (liner) off seal in stages.
Gently press seal without stretching up to start of positioning aids.
Check the positioning of the seal and correct as needed
Firmly press down seal perpendicular to the bonding surface
Pull remaining protective film (liner) off seal.
Press remaining seal without stretching.
Check the positioning of the seal and correct and firmly press down as needed
