The fine wet/dry creates a kind of "cross hatchings" appearance on the plates much like when a cylinder is rebored. Its doesnt make them mirror smooth. I did mine last night. Its more the fact that it makes the plates flat rather than smooth. Use about 1000 grit with brake cleaner for lube as someone above said.
Best diff rebuild video i have seen is here.

I use this exact method, just using a very small smear of the hard grease on the backs of the plates or else it will contaminate the diff lube. As i said, i only rebuild once before outdoor season and once before the indoor season. I use a bit of foam in the outdrive to stop dirt from getting into the thrust race ( foam compensator out of the top of a shock ), and then use diff protectors on the Tamiya too.
A dirty thrust can make it feel gritty, but in my experience, as i always clean and regrease the thrust when rebuilding anyway, its a chipped ball thats causing it. I have Matt White to thank for pointing that out to me some time ago.
