I have tried the Pinnacle Souveran wax on my Brooklands Green NSX.
It produced a nice shine, was a bit differcult to remove. It is a nice show or concours car wax. It takes a little more time to apply and remove. I still use it when I am into a serious detailing mode.
Personally, I have gone back to Zymol NSX wax for every day use. It seems to with stand washing a bit better and is easier to remove and use than the Souveran.
Wax is so subjective. You will hear numerous opinions on any wax product.
Others I have tried Grand Prix very durable, long lasting and PS-21 is another, I like.
