They have by FAR the best wax I have ever seen. It is easy to apply and looks GREAT. It is, however, fairly expensive, and available mail-order only. But DAMN it makes the car look good. You apply it with a simple cotton towel (or their applicator), and buff it off with a cotton towel. All by hand. Doesn't leave swirl marks or anything. You can even apply it in mild sunlight (although even this stuff doesn't work well if the paint is hot to the touch). It's a liquid wax so it's much easier to put on than turtle wax or whatever. It lasts a good while too, and the more coats you put on, the better it looks and longer it lasts.
There are also a number of other Zaino products, one is a rubber conditioner (for tires and weatherstrips) that doesn't break down the rubber like armorall, a glass cleaner (with a mild abrasive, removes those irritating waterspots!), a detergent for washing your car, plastic conditioner, leather/vinyl conditioner, etc. They also have a special wax that removes / hides swirl marks in your PAINT from overzealous buffing with a machine.
I haven't tried all their products but I have liked every one that I have tried. And I've heard only good things about the others.
