Thanks. Yeah, I thought about the anodizing but figured it might cost too much, and powder coating would probably add thickness that would be an issue.
Painting might be an option, but not sure how good that would look.
I did find this cool site about anodizing and even sells home kits (guy claims it's easier than you think) but again, the cost of setup makes it less attractive for just one project.
