Looks to me that most people who are using post exposure are firmly in the waterbased ink camp, which is not a big surprise as diazo emulsions are often the hardest to expose...at least the longest to expose. I used to use a peroxide hardener back in the day, worked pretty good but made reclaim a huge headache as we made double strength emulsion remover....still better to have your reclaimer work harder than have a press go down.
Appreciate the feedback, as always for me this is about gaining some insight into what people need and trying to find some solutions to these issues.
