I've also come to realize that you must wipe a car down with Preparation-H before polishing. Then remove the carrier oils with 3 Grey Goose wipe downs at a minumum. (Of course, all work has to be performed in a heated, down-draft spray booth to avoid dust settling on the finish while polishing.)
As Preparation-H is an anti-inflamatory, you can be certain that your polishing isnt providing a false result. The Preparation-H cream with soothe the paint, thus preventing the heat from the machine "swelling" the swirls closed.
Those magical Menzerna polishes that require 45 IPA wipedowns to show what they are REALLY doing are no match for me!
Dont knock it till you try it...
