Anodizing parts?

[BBC71Nova]

Anybody sent out parts for anodizing? Is it hard to match?

The reason I ask is so many parts today come anodized. For example, say you go and purchase the Ring Brother's hood hinges and clutch master. Beautiful pieces but overall the engine compartment would look much better if you could match that color on other parts like PS reservoir, overflow, accessory drive, etc. That way you'd have a consistent color theme throughout.

Just wondering how that is accomplished. Also, are the parts polished prior to anodizing?

Thanks!
