How to polish chrome pieces

In speaking with mentors Christopher Markley and Tom G . . . I have learned how to preserve the beauty of my dinged-up kick start lever and more.

Tom G. says:

Try autosol for chrome.

For Aluminum, I do the sanding approach, using wet/dry
sandpaper (sometimes I use it wet, sometimes I use it
dry).  220 is a good starting point, but some bad
scratches require coarser grades first.  then 320,
then 400, then 600, then 1000, then 1500, and THEN I
rub out with mothers aluminum polish (although I think
autosol is ok too).
