I have a set of chrome nerf bars that I took off of my jeep. I'm going a new route with it.
I bought them several years ago and they have very minor surface rust if any on the exposed area's the underside and where they mount to your body has a little bit more rust but only surface.
I bought these from a manufacturer as a mis-run, the rubber pads are more towards the front than the back, but they work and look good, especially if you like to hang your foot out while driving. $40.00.....
