You don't need Hutchings' book to get going with PMK. PMK is fairly easy to use, just wear nitrile gloves when developing and make sure to be neat and clean up well. PMK will stain just about anything. You can get it pre-mixed, in kits with powdered chemicals or just get the ingredients separately.
If you end up mixing it from powder (e.g., PF kit) or mix it from scratch, do wear a mask (they're ubiquitous these days anyway) and try to keep airborne particles to a minimum. For instance, I always snipped just a corner of the pyrogallol bag in the kit and emptied the contents into the water with that corner held just below the water's surface. I then rinsed the bag to get any residue. Really helped with dust.
Hutchings recommends an after-fix bath in the used developer in his book that has been found to be unnecessary and even detrimental, since it just builds overall stain. Eliminate this step if you use his instructions.
There is a bit of contention about whether to use a wash-aid with PMK negatives. Hutchins and others maintain that Hypo Clearing Agent, etc., removes some of the stain. I quit using a wash aid with negatives when I started using PMK years ago. Others, more recently, state that wash aids have no effect on the stain. I haven't tested yet, but am happy not using a wash aid for negatives anyway.
Other staining developers, like Pyrocat, work in a similar way to PMK, but the stain is a bit different color. I haven't used them. PMK, etc., are not magic bullets, but the grain-masking effect of the stain and the highlight rendering of PMK made it a winner for me. If PMK ever becomes a problem or difficult to obtain, I'd turn to Pyrocat or Xtol.
Best,
Doremus
