Yes, but it depends on what you're wanting to polish it with.
Gray, fine-grade Scotchbrite works well for the counterweight.
Most body shop supply places will have it.

Combine with your favorite solvent and or/Dawn and hot water.

I usually don't bother polishing anything on a motor but I sometimes do a motor for other people and then I try to make it look a bit more professional. One of my favorite tools is a little paddle wheel sander from dremel. Real smooths and cleans up the face and edges of a crank nice. Not a mirror finish, you would need something finer for that but very nice.
As for the bore of the crank, I make little rotary sanders out of emery cloth and a dremel mandrel. Tricky to use in such a small hole (I learned this technique from sanding thumb holes in bowling balls) but works quite well.

Dremel makes a few different sized green color bits that work well for something like this where you just want to clean and not really remove material. They are rubber or sort of like rubber in material. Mothers mag & alum polish also works as a good 'cleaner' where solvents fail to clean carbon build up from top of piston.
