    I sent this aluminum rail for anodizing and they told me this happened because the rail was improperly vented. It looks to me like something happened in the chemical process. All the pickets have a 3/16 hole drilled internally for venting into the top rail. The bottom rails have 1/4 inch holes in the bottoms, and the top rails are open.
    Could someone with more knowledge than me on this subject tell me if this is a line of BS or what.
