If you notice that one of your car door edges is bent, there are a few things you can do to fix it. The first thing to do is to determine the cause of the bend. Was it caused by something outside of your car, like a rock or tree limb? If so, then you may just need to replace the door panel. If the bend was caused by something inside your car, like a heavy object falling on the door, then you may be able to fix it yourself. First, try using a hair dryer on low heat to soften up the plastic around the edge of the door. Then use a metal ruler or a straight edge to gently push and pull on the plastic until it returns to its original shape. If neither of these solutions work, then you’ll need to take your car into a mechanic for repairs. ..
