Bright color for anodizing aluminum

Hello Folks,

I am color anodizing aluminum for the company where I work, but even when I am getting acceptable results, I would like to get very shine aluminum oxide coating. Is there any suggestion of how to get the parts that nice?

Bright dip, or electro-polish prior to anodizing

You won't achieve this in the anodizing process itself; it must be done by polishing, electropolishing, or brite dipping. Brite dipping is the most common approach but it requires a nitric-phosphoric brite dipping solution which is quite intimidating, requiring as it does a 'garage type' ventilation system, double walled type 316L stainless steel tanks, etc.
