I wax my car with Eagle One Nanowax. It's a liquid that goes on very easily with a sponge and comes off just as easily with a microfibre cloth, provided you put on very thin coats. And you can't screw it up. By the way, from start to finish, it takes me 3.5 hours to do rims and tires, wash, wax, and clean the inside.
I do use Meguiars's Quick Detailer as well - but it is JUST that. A quick detailer, for when your car just needs a quick shine after a recent wash and wax. I would not consider it a substitute for waxing at all.
Some folks on here use some pretty fancy waxes along with a polisher. I'm not sure these cut down on the amount of time you need to get the job done properly, though. IMHO, it's the washing and drying that takes the longest - not the wax. By the way, I also use Mr. Clean AutoDry for washing. Works very well, and leaves no water marks, which can be a pain on dark paint.
Nice cars, by the way.
