Agreed all the way, I'm thinking about making it my hobby to pick up old bike parts, polish them up and resell them at profit. I picked up an old Campy aero seatpost the other day and it was all dull and dirty... with a little fine grit sand paper to smoothen out some scratches, some steel wool, cotton rag and polishing compound, I got that thing back to mirror finish. I could take it even farther and keep polishing away until the thing is blinding in the sun too and I just may... it's super fulfilling to polish a dull part into perfection. Kind of addicting too.
