Need some help as to what my action plan should be in regards to the current problem I'm facing. Long story short, about a two months ago someone rear-ended my car right on my drivers side fender. It created some kind of dent that made my front fender and driver side door hit each other every time I open my door. Now where the two grind together, rust is starting to form. Obviously I can just get a new fender for the drivers side, but what do I do about the door? Is there an cost effective way of fixing a little bit of rust on the edge of my door? Or should I look for a replacement at a junk yard?
