I don't know, I think the biggest problem may be the rust coming through from the back. I think there's also a metal retainer strip in the upper cover that can stream surface rust onto the bumper. Before I replaced my front, I went around asking about re-chroming. That's all it really needed. Prohibitively expensive. For $200 I figured it was worth it. Just went out and looked close at it - it sits outside all the time - no rust anywhere, looks nice and classy. Just use a cotton cloth and chrome polish before you put it on and do that once a year.
