using clay bar on new car for salt residue?

Pavel is right. Once you clay, as long as you keep a good coat of polish/wax on the paint, you should never have to clay again. If you're getting the stuff on/in your paint that requires the use of a clay bar to remove you're either 1) not polishing often enough or 2) not using a good polish. I used a clay bar on my wife's MPV when we got it new in '03 and the paint's just as smooth now as it was then. I apply Zaino twice a year. You can achieve the same results using at the same intervals Classe or Duragloss polishes as well.
