Yeah, I've used the NXT wax on the Trac for years, and have been using it on the Mustang since we bought it. I apply it and buff it our with an orbital buffer. Goes/comes off easy, and leaves a great shine.
Many here tout Zaino. I've no doubt it's a great product, but seems to me to be a little pricey for what you get. Not only that, it takes far too much time to apply Zaino than I have in a busy life filled with child & family activities. It's hard enough to just get a few hours to wash the cars, let alone a little more to wax them every few months.
