    There are hundreds of posts here about how to polish cases. Sorry to be "that guy" that says to search, but my recommendation is to "search" for info.

    That said, my recommendation is the following.

    Remove cases from engine
    Strip off clear coat with paint stripper
    Use the finest grit sandpaper necessary to remove the corrosion damage. 220 grit on a palm sized DA is a good starting point.
    Purchase a sisal wheel and black cutting compound bar. You need some sort of polishing motor to drive this of course. A car paint polisher works well or, obviously, a bench mounted polishing motor.
    For the nooks and crannies, such as around the case screw indents, a stainless steel wire brush on a dremel works well.
    At this point the cases will look similar to OEM level of polish. Some people like a more bright polish so in that case you will need to move to a stitched cotton buffing wheel and fine polishing compound.

    Good luck and hope this helps.
