What is MORE important is the liquid you use to flush the cuttings away from the stones..
I use a mix of 1/4 ATF and 3/4 Diesel..
Hone until you have the wear marks honed out at both the TOP and the Bottom of the Bores...finish, leaving a nice 45 degree cross-hatch..
I tend to use finer stones after most of the Honing is done..
There may be times you will hone each cylinder for 45 minutes to get the Glaze and wear marks out..
Don't worry, it takes a LOT of Honing to remove .001".. just try to Hone equally from top to bottom... Ron..
