I like the looks of the chrome one, but mine has the white spots. I got a PERFECT one from a junkyard about a month ago for about $6.
I used a clean, white, cotton cloth dampened with water to clean the dust off. It apparently has some kind of clear finish on it that flaked off. Now it looks worse than the one on my truck.
I plan to see if I can get all of the finish off and then spray it with some clear enamel or something.
Be careful cleaning a chrome one if you get it used. Oh, and i have seen two new ones bought by friends through the dealer. They have a bronze looking finish that does not look right. They are also around $100. Ouch!
