Now I've discovered how simple it is to remove and reapply anodising I think it opens up a lot of possibilities: You could totally make black VO chainrings with a bottle of Oven Pride and £30.
RE-ANODISE ALL THE THINGS!

Thanks! Summat else to get monkey brain doing overtime.

We did some experiments with stripping and re-anodizing in material science, when I did my engineering degree. The only thing standing in the way of a good home anodizing setup is a good power supply - the amperage depends on the surface area and I think we did one stem, half a seat post and some other stuff at around 8-9 amps..
Also we used pure or concentrated hydrogen poroxide (I think?) and stripping the old anodizing took 2-3 minutes or less.

Think the polished looks better with black rings, one thing putting me off the VO cranks is the lack of black chainrings in the 50.4 BCD, I'm quite content to use the Spa cycles (sugino made) td2 cranks for now.
