It took me about 3 hours (interrupted by watching the race and drinking a few cool ones) to polish up all the chrome. I used 000 (three ought) steel wool to do all the dirty work. I even brought along a few hammers and repaired some dings. To make repairs, I set my dinging spoon upside down on my knee, covered it with a rag (so it wouldn't leave scratches in the chrome) and hammered out dings from the back side.
Not the greatest picture in the world, but you can see an unpolished hubcap on the left (it was too rusted to bother polishing) and compare it to all the others.
