I read that this wax is best for light colored cars. Is this true? I have a dark colored car and I like the depth that carnauba brings. Does anyone know if this wax contains polymers or is it mostly carnuaba based. For example pinnacle paste glaze is best for light coloured cars cause it contains both carnauba and polymers and souveran is mostly carnauba for dark color cars. Also has anyone used thier cleansing lotion with another wax? I was thinking of using thier cleansing lotion with souveran. I was just wondering if their were any bad effect from using the two together.
