I have a JKU Sahara and I don't have the silver plate crap on my rear bumper. I have put on an aftermarket front bumper on but I have yet to replace the rear one yet and it looks pretty bad. I am considering either using a plastic dip or bed liner spray to bring that puppy back. Anyone done this and how did it turn out? I e heard 303 or the ICE stuff but I think mine are beyond that point.
