Cycle for the preparation of polished cast iron prior to hard chrome plating

I have a client that wants to hard chrome plate polished cast iron parts for an industrial application. Since cast iron poses a number of preparation and plating problems I am looking for a fail-safe pre-plate cycle. Your help in providing a cycle that works will be very much appreciated.

Hi, Raymond. I wouldn't claim it was fail-safe, but the only acceptable process for cast iron is vapor blasting, rinsing, plating per Guffie.

Hi,
I suggest Sargent chrome solution and maybe a copper strike.
