Grease on windows

[CJ_Boxster]

Yeah i get that too, usually after i wash the car and the windows are clean, if i roll them down and back up, i see what looks like a spot of grease when a trail leading downward. Also the rubber trim on the outside of the door that wipes water off the window as it rolls down tends to grip the window and calapse as makes the window roll down much slower. hate that sh t!
