it shouldnt from what i have seen. i thought you meant the clear finish would go milky from uv. i dont know if it will still stay as bright as polished but not overly worried about that. i tried some rattle can "ultra ultra hard alloy wheel lacquer" but its ultra something and it aint hard!

Hahaha!

Maybe worth a go then.

I personally would just suggest giving them a go over every couple of weeks or so. Do it as 'maintainence'. Wipe cranks, check chain, lube chain etc.

I run these cranks and also work as an electroplater so have a few toys at my disposal. The best thing to do is polish, then lacquer them. You can clear alocrom them to get a better adhesion for the lacquer. Ideally, polish - alocrom - lacquer within 24 hours. If you build up a few layers and let it set and cure properly between it's going to be the toughest finish you get.
On mine - i just ride them, polish them every now and then. They are cranks, whatever you do will get scuffed.

It's a chromating process to allow a better adhesion between paint and the alu substrate. If you find someone doing it and ask them nicely they may throw your cranks in for a few quid with a load. Make sure you get the lacquer on them in 24 hours though as the alocrom sets as it where.


Edit: o and make sure it's clear, if they offer Alocrom 1200 say no - it's yellow!
