no issues at all. i used dupli-color automotive paint from o'reilly and used my air compressor and paint gun and primed everything and painted it. no issues so far and it looks like it did the day i painted it. has no issues sticking, all i did was rough up the rear bumper a little bit with sand paper, primed and painted it, the wheels i didnt sand at all, i just removed the clear coat and washed it with paint thinner and let it dry then painted it. its all about the prep and paint.
If i were you, id smooth out my bumper myself. remove all the trim, fill in the holes with JB weld, sand smooth, prime, and paint. its that easy, and you will get amazing results. PM me for more input if you need help painting chrome.
