I am new to this forum but it is quite interesting since I have had some experience with Scag restoring Scag columns in a hotel in NYC. We did quite a bit of research to find out how to do it and found the info in Milar's book quite helpful. It is available through Donhead publishing in England. Paid a premium for a reprint myself. I would be glad to answer any questions you may have on how we did the Scag columns in NYC. It has been over 10 years and my memory is a little rusty.
