The factory paint jobs on modern cars are very thin. "As thin as a post it note" as Mike Phillips says. The paint on your car is most certainly a base coat/clear coat system.
One way to find out is to Put a little polish on a clean pad, make sure the car is clean, if you see color transfer then you most likely have SS paint.
My RAV is SS which causes my pads to get messy but I just love how a SS paint shines.
I prefer polishing SS paint over CC, but that's just me.
