These days is it just a pretentious euphemism for "rust", used by people trying to impress others with the originality of their crappy vehicle. Previously used by antique dealers and art historians to describe things like 200 year old furniture or paintings, but now used by Joe Blow to describe a rusted '73 Oldsmobile.
"I blame American Pickers for popularizing the use of the word "patina" to describe someone's rusted, dented and faded old vehicle".
