You have to remove any ferrous bits on any aluminum parts that need anodizing. Also The better the alloy of aluminum the better the results. I worked in a plating shop during the summer when I was in high school. It was a very interesting and dangerous place. We did anodizing in blue, red, gold, green and clear. Plus chrome and gold plating.
