I would say be careful with rust, assuming you scraped off your paint.

The paint was actually already off, removed due to lots of grinding
being done on it already, and because I used it a couple of times on a
grindrail already it's now covered in a slight film of wax, protecting
it from the elements.

I don't see any use to polishing a crank... especially when you're
grinding on waxed metal rails. Can you quantify this "loads of
improvement" you're claiming? I'd say improving your technique
slightly would give you more improvement than resurfacing your cranks.

Furthermore, my pedal makes more contact (surface area) than my cranks
in a grind. Are you going to polish your pedals next? I would think
that would make a bigger difference.

You could be sealing in moisture by waxing the cranks... some paints
(ex. rustoleum) actually displace water and other corrosives as they
coat a surface.

I distinctly sense a smoother 'ride' on the surface, less jittery then
normal, and I can grind a lot farther on horizontal bars. My technique
is probably so, so, I guess someone with better technique (I'm no
street rider) would sense little improvement. Still, anything that is
smooth will win over something non-smooth, regardless of surface.

I could, if I see any sign of rusting, I'm going to clean the cranks
straight away, and use a bit of hammerite on it. It's not like I do
that much grinding anyway.
