i am working on this same problem as we speak on my sons progect,what i have found is you can get rid of alot of the problem (but not all) by rolling down the window, slowly close the door and watch were the rubber starts to contact the door i have found that the front and rear pinch welds are usually the big problem areas. this can be fixed by carefully tapping the pinch welds in evenly, this will take a lot of the pressure off and the door will not pop as bad when you open it. start with the front first, if your door is far from closed and already getting tight look to the front pinch weld area. if you take care of these areas the bottom will asually compress enough to not cause you any problems hope this helps
