Lap the base, do not polish it. To polish the rest, lap it as much as possible, then whip out a bench grinder with a buffing wheel or a drill with a buffing wheel and use some jewelers rouge. I would suggest white rouge up, nothing less if the surface is lapped well on the top and sides, just remember not to polish the bottom.
My block in my avatar was polished using this method.
