I use S&W nonstop and have never had a single problem with streaks (hot, cold, slightly dirty, dusty, etc...). Today, I went back over a car that received Z2 last week. This was my first time using Zaino--I had finally gotten too curious to avoid it any longer. Problem is, S&W streaked something fierce! I followed up with Z6 and it cleaned up nicely, but what is the dilly with S&W plus Z2. Did I experience a fluke?
Thanks.
