Polishing Stainless

[AAAltered]

I bought a set of used polished Mistrals for my 4 stroke. 

They aren't exactly the mirror finish I expected, but I am not sure if that's the way they come from the factory or they need some re-doing.

Anyone have advice for polishing stainless?  I've only ever done aluminum.  I know it's hard to see in pictures....

rouge and a buffing wheel, then a soft polishing wheel to follow up.
