I use a liquid wax on my PW. One of the reasons I use it because i dont have to dodge anything and gets my black plastics/rubbers really black, hit the license plate and frame also. My car has a clear bra over the whole front, including the lights. I also liquid wax that too. I say, might as well...
Here's a video:

But dont get me wrong, the Meguiar's NXT is awesome... but on a dark car (my opinion) so I'm able to see what I hit and missed. And if I had an area where I can spend a couple hours cleaning the car. But I can't at my apartment complex (not allowed). Liquid wax is quick and can be applied anywhere/anytime, including direct sunlight.
