Re: Stainless steel vs. anodized aluminum...

If the part is aluminum and you polish it with Simichrome the paste will turn very dark . . . almost black. This discoloration will occur on the first, second, and twentieth time the part is polished, and is a result of a chemical reaction between the aluminum and the ammonia in Simichrome. Stainless may darken the paste the first time, but that effect diminishes as the part's surface is cleaned. Once the surface of the stainless is clean the paste will remain pink.
