I have mine done with I think Spectra I do not recall. I dont have a pic handy but you will like it, it looks like chrome unless you walk up on top of it and really examine it. Obviously you can tell if you look up close and examine pretty hard.

I have lot of fun when people look at the car and I go "check this out" and grab and slightly flex the bumper - every single person that has seen my car assumed they were regular ole chrome metal bumpers and has their mind blown....
