Kona Kapu

Yeah its defo an anodised finish. While its still fairly bright, anodised silver parts tend to have a slight matt effect compared raw/polished alu.

@Hulsroy My thinking was that without removing the machining marks, even after polishing it might still look a bit dull. I have a professional polishing wheel and done my mtb cranks that came out really well here (soz, not that its competition!)
Polishing with the wheel in its self I suppose would flatten down the machining marks a bit. My worry is that removing them with wet and dry paper might make my 31.6 seatpost closer to 31.5!? The wet and dry sanding part also takes way too much effort.

I think I'm just going to give it a bash
