I rattle canned mine 2 1/2 months ago. I have been down dirt/gravel roads, car washes, highway, and around town; no need to touch up yet. I have not rubbed them up on any curbs or bounced them off any rocks yet, and I am certain that would cause a scratch or two.
Wheel Pics
Take note, it did take several hours to paint all five wheels. Money is harder to come by than my time. So if I had too, I would paint mine again instead of Teflon or Powder Coating my wheels.
