Well since I sold my black G35 back in December, I hadn't used this car wash again on my new car until today. I forgot how much I like this car wash! I bought it from CMA upon recommendation for a carwash best suited for a black finish. This was suggested to me and I was completely satisfied with its performance. It has very high lubricity ( I think NXT wash is slightly more slick), sheets the water right off, and has great cleaning ability. It might be a tad bit harsh on a carnauba, but it seemed to have worked great with my month old WG sealant. If there is one downside to this wash, it's the price, but if you're only using it on your own car once a month or so, it's pretty reasonable. This wash is definitely one of my favorites.
