I have a spray bottle of Turtle Wax Spray Wax, a huge jug of Meguiars D156 (Express Spray Wax) which is just the professional version of their Ultimate Quik Wax, and a bottle of EagleOne Spray Wax. They all work great, are easy to apply and buff off, and provide a nice shine. My personal preference is Meguiars for a quick spritz, as I find it easier and faster to buff off, but I feel that the Turtle Wax and Eagle One provide a slight advantage in terms of appearance, but require just a little bit more work.
Eagle One's nano wax is a terrific product. You should consider it as a 3rd option.
You honestly can't go wrong with any of them.
