Megs OTC clay kit will get the job done, just be careful not to mar your finish, use lots of lube.
Each one of those has a strength and a weekness.
Carnauba waxes (good ones) usually come in a paste that ranges in hardness, carnauba offers the wettest, sharpest, deepest look, but isnt the most durable option for protection, usually get 4-12 weeks on average before you need to reapply, some last longer and others shorter.
Liquid waxes may contain carnauba wax in their formulation by weight or volume, but are different in composition.
Liquid sealants (non otc) are synthetic in their makeup and offer a look that is almost as good as a carnauba, while they dont look quite as good, they are very durable, most good sealants last 3-6 months strong some longer.
Alot of people like to seal their car with a synthetic sealant, and once its cured, top it off with a quality carnauba paste wax. This is a great combination of great protection/durability and that wet/deep look that a carnauba offers.
