My LTZ has had a small rust spot forming on the front bumper since I got it. Next time it goes in I'm going to see what the upcharge would be for getting a painted bumper put on instead since its getting replaced reguardless. Yea, I'll have a chrome rear and painted front bumper for a while untill I get that sorted out though. but I was looking at it today and that may not look too bad since the front has that giant chrome bumper insert anyways, so theres still plenty of chome up there.
