annodize vs powdercoat

[bobcowan]

Anodizing places a dye kinto the underlying material. It's often not very durable, and can easily be damaged by nicking. There's no way to repair those small nicks and have it blend in.

PC actually coats the part, like a paint. But it's a very tough material, that's also flexible. When you do damage it, it's fairly easy to repair.

I agree with Bob that powder coating is the way to go. There are 2 types of Anodizing for Alum. 1. Hard Anodizing is a very hard coating that is that actualy builds thickness of .002 at a min. The Problem is that is does not dye well. 2. Sulfuric Anodizing take color well but is not very durable because the coating adds just .0002 of thickness.

I prefer the anodize but if the spinners are cast rather than forged or bar stock you'll probably end up with a blotchy irregular coloring.
