Just hit the exhaust, hubs, axle, and some other parts with some CLR and a wire brush. Look at the difference. Its almost like new!!!!! Ill do a how-to right up when I get my pipes in. This stuff is amazing!
I'm actually not in IN. I'm in Illinois. It's about an hour and 45min from where I live, just across the IN border from me. From the way the map looks it would be a lot further for you to drive than me.
