The absolute best stuff I have ever used, (and I have used all the simichrome and mothers and flitz out there) I'd stuff called Rolite supra 90. You can find it online, at aircraft supply places. My neighbor is an airline mechanic and he gave me an old can. They use it to polish the airplanes. I polish aluminum to a chrome finish for a living and nothing even compares to supra 90. It's in a class all by itself. The other stuff is decent but it's a distant second place. Just Google it and you'll find it. It's amazing. Also if you can find something called Sunshine polishing cloths those are equally amazing. They are available from Rio Grande. It's a jewelry supply place. It's a bit of a pain in the ass to get the cloths but if you do you will be amazed by the results. Combined with rolite, you better get a fresh pair of underoos, because when you're done polishing you'll throw it in your own net.....
