Great move going with Zaino. Just spent the weekend on my wife's car. Time consuming the first pass but the effect is worth it and maintenance is incredibly easy.
If you rub your hands over the paint and it is not smooth as glass pick up their claybar. Don't forget Z6 for removing the dust and pollen, water spots etc. in between washes. And don't forget their carwash and applicators.
It may seem like a lot but it all works together for a common goal and the car will look incredible. Even with all my paint chips the thin Subaru paint looks great and I always get comments
