1. seal (Fk1000)
2. Wax of choice, Natty's (short term wax, better depth) or Collinite (long term wax, less depth)
3. Last step product (LSP) like FK 425 spray.

The carnauba element in a wax usually means it will have a wetter shine but carnauba is a natural element that will not fare well in rain, sun, etc. like a synthetic wax. If you use a high carnauaba paste wax you definitely want to top it with FK 425 spray to get more longevity. But to be honest its only really on dark cars that you can tell the wetter shine difference and even then it takes a good eye to tell them apart. You can use a synthetic wax for duarability and simply boost it in the short term with a spray that has a fair amount of carnauba like Griot's Spray Wax if you want to keep the touching to a minimum (a good idea with dark paint). When it comes to carnabua sprays and paste waxes, you can almost smell the carnauba when its highly concentrated...or simply check the price. LOL.
