It also depends on the anodizing and type of process they use if you can get it off. Typically even light anodizing permeates a little bit of the metal so you would have to remove all of it to be able to polish it. If an item is hard anodized which is typically clear but creates a rather grayish tint to the aluminum you will not get it off with EZ off. It actually permeates and strengthens the aluminum around .003 of an inch.
