Hijacking is ok!  I have learned a bunch about what to and what not to do!  Got a compressor from a friend that would push a sodablaster.   It doesn't seem to get all the way down through the oxidation, but looks much much nicer!  

I like the idea about brass rotary brush between the fins.  

Also I have found that with a grey stick polish and a rotozip with a 2" felt disc I can turn any aluminum surface on the bike to a mirror finish.  (Portion below and above the gasket looked the same)  The trick is getting the polishing head all the places you need for a clean cut off line.
