I recently bought a four step wax kit for black vehichles. Made by Turtle Wax and called BLACK BOX. Found it a my local Autozone. It has a Black pre-wax cleaner, Black spray detailer, Black carnuba wax, and application pads. I was verry impressed with the results of this product. Black wax and cleaner will noot leave white spots on your plastic trim if you accidentially get some on it. It leaves a beautiful shine (looks really deep). It is supposed to return the paint to a like new appearance ( for faded paint ). I cant attest for that as my paint is in great condition. I wax it every other month but not with this stuff. It took around five hours to do my truck, but it was so worth it.
I do recomend using rubber gloves with this as it will leave black around your fingernails and cracks and cuts ( found out the hard way ).
