White marks rear side windows

[Vinootje]

How can i remove these white marks in the side rear windows?



i have readed that taking the winow from the car and wet sanding the black part until the white is gone and than respray with black primer, can anyone confirm this or has better working methods?

Its basically the "paint" or whatever it is on the rear of the window thats worn away by the rubber strip, so technically repainting it should work. maybe try a small amount of paint on the rear of the window where the white line is and see if it darkens it from the outside before you go to the effort of sanding it all down etc.
