NAPA 4" hone stone grits

[Hemlock]

Hello all,

I've been reading a lot here in the last few days, great site an tons of good information. I have a question I can't find the answer to by searching: What are the grits of the NAPA 4" stones for their cylinder hone?

I've got Fine, Medium, and Coarse from Cripes. I need to refresh the bore of a cast iron two stroke top end, and am unsure of what stones to use. The fine feels too fine to me. Do any of you have experience with these?

It depends on the material of the rings you are using. the info is out there, off the top of my head I cannot remember which is what, IIRC cromoly is finner grits like 320-400, and the iron rings use coarse.
