I started with a Dremmel to take the bulk of it down, then pretty much used whatever I could find to finish it with. Used some 60 grit, 600 grit, 2000 grit. Also used a flat file a little. Used some cloth, and #0000 steel wool too.
It's not perfect, but looks Damn near factory. I wish the pics were bigger.
