    Nope, both of my chairs are raw uncoated aluminum and no issues. The oxidative layer is very thin and just makes it slightly dull while the wear points stay very shiny. I get a bit of a black smudge in a very small spot on the sides of my legs when wearing shorts where my legs rub the front tubes but that's it.

    Ahhh, gotcha. fwiw, I'd consider black smudges rubbing off my chair on to me an issue, but it takes all kinds!

    A thin layer of oxidization is almost like a finish in itself.

    Does it pick up scratches easily? What Al alloy and temper do you use? Assuming this is a custom...of course.

    I wonder if the automotive aluminum polish would minimize the oxidation/residue? It's supposed to work on car wheels. Hmm
