I apologize in advance to anyone who declares me a heretic for altering the original finish on a Campy part... I like the shine on a new-looking part that requires additional polishing effort over the dull glare of a original finish.

Please correct me if I am wrong, but I thought to "anodise" Campy parts meant to coat the alloy metal in a protective black coaating. The anodised finish is a real bear to remove manually or by chemical means - unless there is a constant rubbing motion that literally "wears off" or scratches the finish. The protective coating applied to Campy parts appears to be a thick clear chemical that almost seems to bond to the metal.

However I have a question about how to completely and easily remove the clear protective finish applied to 70s era Campy parts... In the mid 1970's, Campy started to apply a protective finish to inhibit Campy alloy parts from dulling. I have several older parts that have "gone gray" in color because the alloy has discolored with the decades, even though the protective finish remains. I have only been able to remove this dull finish with extended use of fine steel wool. Alloy polishes such as "Mothers", "Simachrome", or "Met-All" do not seem to have any impact in polishing the alloy because they cannot penetrate the Campy protective finish. I wonder if a semi-abrasive like "Brasso" for alloy parts may give better results... any suggestions?

Thanks, Steve Neago
