I do that for fiber based paper--use 2 fix baths at Kodak paper strength (non Ilford sequence)--kodak rapid fix A, no hardener. Go from the second straight into selenium mixed with permawash. Some papers do stain though--in which case I've used a reg. plain hypo bath for the second fix,or mixed in Kodalk or sodium metarborate.....for RC, I do a 2-4 minute wash and then tone follow with a 5 minute final wash. BTW--this is how I do it mostly now, and use machine processors as well--turn off the dryers, go to a prewet, tone, then wash.
the secret is to not have dry patches or areas without fix on them when the print goes into the selenium toner--otherwise, staining may happen.....I usually just barely drain the print & then go into the toner.....
