I have a ton of b/w rc prints to make and so I'm considering running the prints through my fujimoto roller transport machine. Does anyone have any experience with this? Does chemistry dedicated to rt work better than others? Is a stop bath necessary? I'm considering Ilford's 2150 kit but noticed that other b/w developers have working temps between 65 and 90 degrees f. Also, I'd like to use a hardner with the fix to keep scratches down to a minimum. Unfortunately the 2150 fix is hardner free. This makes me wonder whether hardner has an adverse effect on the hardner.
