Can You Change The Color Of Anodized Aluminum ?



(-----) February 18, 2008

I want to change the color of silver anodizes aluminum to red or blue. Can this be done?

Anodizing is a chemical bath process and can't be done while inplace. Have had success spraying with metallic auto paints. Good luck

The "color" on aluminum is obtained by dipping a freshly anodized part into a vat of water-soluble dye (lots of available colors), then it's "sealed" with either boiling distilled water or proprietary chemicals. Once sealed, the aluminum surface is, for all intents and purposes, permanent. You could have the anodized layer removed with a deoxidizer (all anodize shops have this capability), then re-anodized and dyed the color you like. It's definitely not a DIY project.
