It's really a personal preference between chrome and bare metal.
I know some folks prefer the chrome, but I find the polished bare metal finish looks more like the real thing. However, bare metal may be more subject to splotching or darkening over time.
I bought mine on ebay without first educating myself on what Jet-X had released.
Seeing the post below made me realize Jet-X made a bare metal version of the straight AA livery which is what I wanted.
