off time after time (not a permanant fix) and make a lot of towels black (in my Z's case) that you really can't wash unless you want your washing machine to go black on the inside (trust me, I know this story all too well!)
Its good to have handy and does make the car look nice, especially if your paint isn't in showroom condition. Since it is a polish (if we are talking about the same turtle wax product) use a few coats of a quality wax afterwards to protect it and to increase longevity.
