I am debating whether or not to top the Prime and AJ on my two cars that are white and silver with a carnauba wax and am wondering what you all would do. I have 3 coats of AJ on the silver car and will have 2 coats on the white one. I'm thinking either NXT paste wax or S100. I am leaning more towards the S100 due to eaze of use and slickness. I have never used the NXT before, but I have heard that it stains trim. Is that true? Which one is better from a durability and shine/depth standpoint, although I'm not really concerned about durability since S100 is ridiculously easy to apply and buff?
