I use KoolMist formula #78, which appears totally inert and harmless (stains a little if you let it dry, though).
My only complaint is they didn't have any good requirements for air supply, so I bought a compressor that was too small and had to upgrade. I now use an 8 gallon, 2HP, 4cfm@90psi oilless compressor from Harbor Freight, which is located about 40 feet away in a separate room for noise suppression and so it's on a separate circuit from the mill (prevents browning out the mill circuit and causing missed steps). Works great when I keep the supply pressure at about 35psi...above that and the FB oscillates when it first starts up. As I said, worth every penny, IMO.
One caveat: be sure to align the FB each time you change cutters. I broke about 3 of my 1/32nd cutters before I realized the FB was pointed too low. It appeared to be working (saw coolant flowing) but it was cooling / blowing on stock rather than the contact point. I now use an inspection mirror and sight up the FB's nozzle tube from below the cutter to make sure it's pointing at the cutter contact point.
