I recently acquired a large lot of fairly recent PPF 120 that was (and is)
in cold storage, so I'm interested.  The rub is that I've stubbornly
insisted on doing everything in PW and don't have PS.  If you can explain it
in generic terms, I'm confident that PW can match the procedure, as long as
I can hold up my end of the process.  I'd be very interested to read about
the technique. No doubt others who use PS would be interested as well.

Sincerely,
