Re: Zaino is good
... but can be pricey. I have used it on the Saab and am very happy. I plan on doing my Sapphire Silver coupe with Zaino soon. As the finish is still real nice, the Z-2 will do a great job. The saab needed the swirl remover, then the Z-5 (which helps conceal imperfections.) But you must wash with blue Dawn to remove all the old wax, then clay bar the car prior to any Zaino.
Put your hand in a sandwich baggie and lightly run your fingertips over your paint. It will feel like sandpaper. Then do it again after the clay bar treatment and you will be amazed how much smoother your paint is.
