I think they are anodised...
I assumed he used the emery paper to remove it instead of caustic soda, wasn't very clear there, obviously it removes deeper marks, and sorry Malaysian, I'm pretty sure anodising doesn't happen over time and does indeed require electricity.
Saturday night, correcting people on the internet, when I'm not 100% sure anyway, dream big.

caustic soda didn't work, used same concentration that stripped my chainring ring in seconds, they only thing that started to react was the threads, not ideal... so promptly took it out and got to work with emery paper, not great for getting in the milled bits, but with a bit of elbow grease, i'll get there... also used autosol to polish it up, amazing stuff!
