Not really. It's pretty thin and weak. A lot of them do contain some type of carnauba wax but a lot of them also contain high amounts of silicone. They aren't trying to "wax" your car for you. They want to use as little as possible and make the most $$. You get a little shine from it for a couple days. Some of the clear coat "polish" or "protectants" are just silicone sprays that help to break the surface tension of water so you get the same beading effect you would from a good wax. It also looks shiny.
A lot of the chemicals are formulated to smell nice and foam up a lot. It's what people want to see and they feel like if its really foamy its doing a good job. Those are actually the selling points on some of the chemical mfg websites for carwash supplies.
WarsawChem is a big supplier. Their website actually has decent amount of easily found info on chemicals.
