In my opinion I would stay away from wax's and head for the polish. Your car has a clear coat over the base coat which was designed so that the sun would not fade your paint as quick however back in the old days and in old skool shops like the one I was working in the paints are single stage. Single stage paints provide all the shine but not very much protection from the sun so they would wax the crap out of em. Long story short the wax is an over kill and will end up leaving alot of buildup on your car. A good polish, not a wax, and some hard work will make your car pretty again! 
Hmmm... Clear coat is a ceramic coating which in theory, should't need any further treatment... However, as correctly suggested by Purple Haze, it does degrade over time and sealants and waxes protect the paint, and also magnify the gloss brought about by polishing. Please correct me if im wrong but i would ALWAYS suggest to protect the paint with a sealant or wax.
If you dont want to apply and wait half an hour for it to cure, you could always use one of these "apply and walk off" products like GTeqniq C2 or Opti-seal which will use nano-technology to bond with the paint. I recently got some GTechniq C2 which i applied to my bonnet today, so i'm interested to see the level of protection/beading i get from it when it rains (which will inevitably be when i get it out of the garage tomorrow morning!)
