Ice Car Polish What Should I Do First? Polish Or Detail?

What should I do first? Polish or detail? - ice car polish

I stick Polish Turtle Wax Turtle Wax ICE and ICE Spray Detailer and I wax my car. What should I first? I sanded and then sprayed the Detailer, or should describe in detail and polish? And I need a real boat that says, "wax" or not?
