There is patina and everything else is a paint job, solid shiny from flat to deep toned pearl to fake patina. Real patina will never go out of style now that it has picked up on as a style. Back before that, about no one got it. First comment would always be "When ya gonna paint it" or "That thing needs paint". I've always done trucks (except restorations) mechanical first, then see about getting shiny, and loved the ones that never got there just as much as those that never did. A smooth running machine is a smooth running machine no matter what it looks like... unless there's a bunch of crapped out sheet metal flappin' and vibratin'
