Roger -the MB-20 should work well on the serpentine-use it as your final polish.Like john says diamonds to 1800 then for vertical surfaces try the MB-20 after honing. For floors after 5x or a pinch of MB-12 will usaully do the trick. On vanities after diamonds and 5x use the MB-20.
We have sometimes used Dehumidifier from Drieaz. got some old one like the number 80 and 110 driers to dry the floors faster.
Lay plastic on the floors and run the dry air under the plastic, room can get as hot a 95 and moisture air reading of about 25 when the floor is dry.
The moisture reading will go up and then drop as the floor drys. Used newer units like the 1200 and bigger to dry faster. You need fans to blow air on the floor under the plastic. Just like when you have a water loss and they dry the carpets. Hope this helps

Baird,
Depending upon how much moisture is in the stone, have you placed fans on the floor to dry them , how much water did you use when honing the floors, was there any missing grout where moisture got into the stone, all these will make a difference on the dry time. If possible I prefer to crystallize the floor the next day. The reason for the darkening is the moisture and the Steel wool reaction.
I’m currently working with a product that acts like a crystallizer but there is no need for the use of Steel wool, you can polish with a white pad or hog hair pad. hope to have this in the next month.

Hi. How long do you all let the floor dry before crystallizing? I often run into a problem with the crystallizer darkening the stone, which means that there is too much moisture in the stone?

Going up to 3000 is over kill, the serpentine has some calcium in it so there will be a polishing reaction using the 5X polishing Powders. The crystallizer will just give it the final pop to the finish.
Also not all crystallizers are pink.

We start at the appointed grit, carry the grits to at least 3000, then granite polishing paste, finalize with the pink stuff.
Good luck

Looking for suggestions on handling this job. Honing followed with MB 20 or should we just use the pink stuff on the stone?
Thanks,
