I have had pretty good luck polishing the cylinder bores using
3M scotchbrite pads. I cut a disk approximately twice the diameter of the
bore. I have a 3/8" X 6" steel rod which I have drilled and tapped on one
end for a screw. Punching a hole in the center of the scotchbrite disk, I
screw it on the end of the rod. Then I just chuck the assembly in my drill,
soak the pad in brake fluid, and polish away. This quickly leaves a very
smooth surface with no visible honing marks. If you use a coarse pad
and grind at it for awhile, it will remove some metal, especially on
aluminum cylinders.
BTW, to give credit where it is due, I think I picked this trick
up on the Brit-cars list a couple of years ago.
