Sounds like typical dealer bullshit to me.

I have a proper dealership paint protection kit sitting at home, and its just 2 bottles. Paint prep and paint polish. Apply with foam applicator, wipe off with microfibre cloth. Single car use, cost price is 70 dollars. Dealers charge from 500 up to 3000 depending on what make I.e. You'll pay the higher price at luxury dealerships.
