The piece of thin metal about 2 inches wide that runs under the doors and body of the car (near where the car is jacked up) has completed rusted on the driver side of my car. Is that part of the rocker panel? Can that be replaced or a new metal strip welded on? What's it called?
I don't believe it supports the car since it's so thin (maybe prevents scratching the paint bottom when on a lift). I also noticed that if that piece completely falls off there will be an open gap just below the door hinge where the door closes. It's starting to hang down now and I suspect will fall off soon and want to avoid water getting in the car.
