It looks like I'm just going to have to try this Pyrocat-HD stuff. It certainly seems a lot safer and more convenient to use than ABC. Cheap, too. I'll make it part of my next order to Artcraft.
Do you find that it yields less general stain than ABC? I don't get much now, just about the same as with TMax in TMax RS developer, so I'm not sure this is even an issue for me. Certainly nothing like the pea soup fog stain I get with PMK.
