This is an email response I got from them:
I've done it in red. it looks like crap, we spend all that time finishing the hub soooo nice and then it gets a rough powder on it that fills in the logo etc.
If you want it you can have it, but you've been warned. It will be an additional $150 whether it is one or four hubs.
Let me know if I can help with anything else.
A rough powdercoat? I've never seen powdercoating that came out with a rough feel.
