Talked with Zaino over the phone today. I have a dark blue car with minor/light scratches that I would like to get cleaned up. Zaino recommended first applying a couple of coats of Z5 because in so doing, it would fill up the scratches. Only recommended using ZPC if Z5 doesn't cover it up. Isn't that just hiding the issues? After some washings won't the filler be removed and I am right back where I started? Would I be any better off to use SSR2 or 2.5, or some other product before going with the Zaino system? Bottomline, I am confused between using a filler to hide the blemish versus an abrasive product to eliminate or reduce the blemish. Any advice or thoughts?
