Phil: At the risk of being obvious, I remind you that results can vary widely with the alloy being treated... more alloying tends to give worse results..

Hexavalent Chrome Alodine or Iridite conversion processes are being replaced with either a Trivalent Chrome Process (TCP) or Non Chrome Process (NCP) for surface treatment of aluminum (aluminium for the Brits out there). What good, bad or ugly tales do you have? I know fingerprints are an issue with some platings. Has anyone changed processes and run salt spray tests? What were the results? I'm trying to put together some supporting (or refuting) data on possible chemistries for conversion coatings to be able to defend our change decisions.
