I have a line on a pair of wheels that have been fully polished...

What's a good method/procedure for toneing the polish down? I know this has been discussed before here. Perhaps a link to that previous thread would suffice? I'd like to be able to take care of this myself v.s. shipping them off to the pros (Harvey, Al, etc)

Anyone? any "been there, done thats"?
Thanks
Cheers
Thom
