I know the rust, born and raised in NY. Brought my ZJ out west with me. In June I put a custom suspension up front and the arms were set a bit short so on the trail I had to hammer down the pinch weld and the inside corner of the fender. When hitting it with the sledge I hit a spot and the hammer went right through a nice rust spot. I have "custom air holes" in my hood, two rust spots that go all the way through.
