A couple of days ago my GF's father backed into my car by accident while exiting on the steep driveway to go get some groceries... I heard my door fold in and out like a soda can in slow motion *terrible sound*. Right now the huge dent fix and paint labor is said to involve replacement of body panel for the door and painting/blending the side with 3 stage paint. Anybody had this kind of repair performed in the car? any pointers as to how to spot paint/replacement issue for this? i'm scared the final repair not being perfect
