Typically, I like all the products from mother's. I used to be a Maguire's guy, until I was a friend "showed me the light". Mother's products are without a doubt the best you can get at Autozone or the like. Their "show time finish" looks and smells so good that sometimes I'm tempted to drink it.
But as spdfreak said, Zaino is the way to go. I've seen a few friends cars that have thew full zaino system on it, and the shine will change your religion. Granted, it is relatively expensive, and not available in stores, but I've never seen a black car look like a mirror. The shine is so high, that the paint is almost as reflective as chrome. After seeing a few cars using it, Zaino will definitely be my next purchase.....
