Urgh, still not got round to doing this... I guess the next chance will be at the end of the month when the bike goes in for a service for 3 days... Annoying.
Having worked in a place where we had 99% of our aircraft grade aluminium components anodised I'd suggest you didn't bother. Results vary from piece to piece, we would never get a consistent colour from any batch. Absolutely no idea why but it can go from looking good to totally shite. Powder coat it, it's the new anodising.....
