Sheena, with the Zaino products, you really need to apply them by hand. I'm not sure you can correct swirls with them. I believe they are more for getting that deep wet look. Honestly, they say 1 oz does the whole car. And it does! One of my coworkers tried using Zaino like he would McGuiars and it took about a week for it to dry for him to get it off.
Follow the directions to the T. If you don't think it's going on the car, rub a spot on your window with the applicator. If it leaves a streak, it is going on.
