You will remove contaminants if you clay bar a new car, so I would recommend it. I took delivery of a Jet Black 330i in March and started with Zaino clay bar, followed by Z1/Z2. You don't need to use the Zaino clay bar with the Zaino system, you could go with Mother's or another brand. The car has been through a lot by the time you get it and you won't be disappointed you bought the clay when you see what it pulls off.cflammi said:
