I'm going to try some 2nd pass lith using Moersch easy lith. Should I use the same dilution starting points as for regular lith printing or should it be different? I think I usually have started with 25ml A + 25ml B + ~950ml water. Though I'm kinda guessing 'cause it's been too long. If paper makes a difference, I'll probably be using Ilford papers - mostly warmtone FB.
Ilford WTFB can work well. I've not changed the concentration of my lith chemicals for re-developing. You will increase the contrast, and could lose highlight detail.
Here's one of my experiments:
