It is not the time pressure is applied, 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.

Clean bonding surfaces on paint with adhesive remover (sourcing reference: BMW Parts Service).
