I checked it out last night guys. Here's the deal.... I had 3 of them. One I put on my car. I unwrapped the other 2. One is a stock piece (black), apparently never used. Now I recall I bought a brand new one and chromed my old one. I thought I chromed both of them.
The 3rd one IS chromed. Although it has no pits, tarnish, etc. and has never been used, I would not call it "show chrome". When they plate chrome they put a nickel finish on first. This piece has some of that nickel "wash" in the recessed/corner areas of the cover. It's more noticeable when you move it around and see it in the light. It looks like a light "tea stain". I've seen it before on chrome parts that have recesses and nooks and crannies.
Now I recall what happened. A list member hooked me up with the chromer he used. When I got it back I was not real happy with it, but I didn't want to give the guy a hard time because I didn't deal with the chromer one-on-one.
I'm not sure I could even capture the "stain" in a picture. I know I was disappointed between what I paid for the cover and then the chroming price!
