My right door roll-up window is fouling on the back of the window frame and chipping the paint. I did some investigation this weekend and found that the door as a slight bend, not a dent, but a full bend that is causing the window to not align properly. The bend is very minor, but it looks like someone has tried to fix it in the past as there is a lot of bent up metal under the door card. Does anyone have any advice on straitening the door? Can a shop do this? or should I be thinking about a new door?
