The whole process of polishing them only took me about 20 minutes. I used a little too aggressive sandpaper as I was out of what I usually have
-1000 or 1500 grit sand paper
-Rubbing compound (I use turtle wax, any brand works)
-Polishing compound (turtle wax again, but crappy quality IMO)
-Mothers Mag and Alloy Polishing Compound (this is a MUST),
http://www.mothers.com/02_products/05100-05101.htmlThe mothers is the trick. Its some of the best compound Ive ever used, I know there is better stuff out there, Im just not sure what it is.
Make sure to use microfiber/flannel rags for the final polishing. The copper is real soft. Even the rags alone left superficial scratches in the surface. Though none of which showed up in the photos
