I wouldn't recommend stainsteel trays for any toners. They have reactions to many of the various chemcials used in toners. In fact, we just use the stainless trays for warming baths and don't use them with the standard developers, etc; and this is with photograde stainless steel trays.
This is a great toner and like all of the more exotic toners has a mind of it's own, with the results being unpredictable especially when allowing the print to split. Toning to completion is pretty straight forward.
I will second donbga recommendation about Time Rudman's book as a reference guide.
