A guy with a 31' Contender I met at my Marina uses Zep Stainless Steel Cleaner which you can buy at Home Depot, he swears by the stuff and it's cheap about $4.00 a bottle.
Call Woodies wax direct. They have some pre treated spounches for this. The Brass wool may still be needed. I have some samples if you are in the Cohasset area email me at tom@mtcfish.com
