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.

Anodizing is the only way to go.
- Hardens surface - never scratches
- Good color
- Permanent

I agree that anodize is the best thing to do. Yes it puts a small thinkness on the part but it is very durable.

The down side of powder coating is a chip allows moisture to get underneath and corrode with no visable indication.
A lot of later xj6/xj12 had the lower front spring support powder coated, and the first sign of trouble was the spring hitting the ground. And we don't use salt on our roads in NZ.
