I was impressed with the dust antistatic feature of the Z6. We just had a major rain storm here yesterday and the car doesn't really look dirty at all today. Before the Zaino, there would be a hazed layer of dirt and dust all along the bottom half of the car.

Oh, and another thing. So I have the base coat now but I still see some swirls. Now I can live with the little amount that I have but say I want to decrease them some more later on. Can I use Z5 over my previous coats (even though there are Z2 coats) or do I have to strip everything down and get all my swirls out with Z5 before going to Z2?

 

You can continue to use Z5 to try to hide the swirls. I don't get too worked up about swirls as they will always eventually come back. But if it really bothers you, you will need to use a genuine scratch and swirl remover with a auto power buffer. This alone will strip off whatever you've got on there. Z5 will only attempt to "hide" swirls. The only way to remove swirls is to buff off a small layer of paint.
