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.
