I have no experience caring for bare aluminum cars. I do however have a ton of experience caring for bare aluminum airplanes. The kind that are flown and displayed at airshows and I can tell you with a level of certainty that between rain, bugs and the sticky fingers of children that bare aluminum does just fine with a little maintenance. We did a big polish prior to the first show of the year and the rest of the time it was a case of wiping off the worst of it at the end of the day. Zero oxidation, ever.
