Actually, you might want to reconsider using wax on a guitar (though you certainly can), for a few reasons:
1. All waxes create yellowing to a degree as they oxidize. If you have a car, you need to protect it from road grime, bird droppings, acid rain, and other stuff. This is where a wax makes sense. Or a floor, where shoes trod on it. A guitar doesn't see this kind of wear and tear.
2. Most guitar polishes contain a little surfactant and get plenty shiny. The PRS cleaner leaves a very shiny finish, by the way, and it isn't an abrasive polish.
3. Carnauba is the hardest wax in the world. In its raw form, it consists of hard BB type pellets. In order to make Carnauba pliable enough to actually use, it must be "cut" with some fairly strong petroleum products. Again, this is fine for a car, as the Carnauba leaves a strong wax finish. Whether this is good or bad for a guitar is not for me to say, but combined with the way Carnauba yellows, it doesn't seem like the world's best concept, and since it isn't really necessary to use something like this on a guitar, you might want to reconsider.
Probably most guitar polishes contain a little petroleum product, to act as a surfactant for the solid materials in the polish, but not like Carnauba waxes made for cars.
I'm told that PRS uses the PRS Cleaner to clean up the guitars and make them shiny for when they're shipped. Maybe Shawn can help with this info?
Incidentally, your '13 PRS is V12.
