I polish lots of parts to a mirror finish. It takes more than a tube of autosol to do it properly.
I now use a bench grinder to do the work but when I started out polishing I bought a kit with a drill attachment exactly like this ebay auction http://cgi.ebay.co.uk/12-pc-Polishing-Kit-for-Brass-Copper-Iron-Steel-Alloy_W0QQitemZ180109010983QQcategoryZ25644QQrdZ1QQcmdZViewItem
What you do is use the course mop on the drill with the appropriate compound, this does the initial polishing. You then use the medium mop and compound and finally the fine mop and compound. After using all of the mops then the item should have a mirror finish.
It takes a while to do it properly, for instance a set of crank arms take about an hour to do well.
