I noticed a few small areas of my frame have been polished and I was wondering how some of you guys did it. I think my bike would look pretty nice with the whole side of the frame polished.

 

this is the most in-depth explanation i could find.

Its a little weird, but accurate. I wouldnt use an orbital sander though. I found that hand sanding allows you to be more gentle and keep the swirls out of your frame. Just take your time and you should be fine. Just find a lot of friends to help or this will take you forever, trust me.
