Memory serves me as DC stating itself as a pure wax. I won't even bother asking the percentage and grade of carnauba it actually contained.
It worked fairly well for me in the past. Of course I've learned a little bit more about waxes since then, but all in all I think that the 3-step DC is fairly good for an average over the counter cleaning system. You shouldn't have problems with maintaining your clearcoated surface if it is in immaculate condition, as I've used Meguiars DC for several years on my prior car that still has its showroom shine.
Durability I have found that to be more of a subjective term. A lot of people commonly mistake carnaubas as not long lasting, whereas I've maintained my resolution and build-up for months with no problem (It also helps to put on and buff off the wax properly, not caking on excessive layers at a single time, and allow a little time for it to dry).
