well i been on the computer and i ran across a product called white diamond metal polish for gold,chrome,alum,stainless.its what alot of truckers and motorcycle guys use .it works like most polishes but u let it dry before u rub it off .from the reviews it leaves a thin coat of sealer behind to keep it shining longer .sold at advanceautoparts for 15.00/12oz bottle.i know mothers mag polish works well but it doesnot seal the shine in .they also sell this in a handy little wipe to get into tight spaces
