2015 S65: CQuartz, Opticoat or ???
One can "wax on top of those" but you cannot polish. I prefer to get a deep polish into the paint ever six months with a great wax job after.
Never found much use with either.
PS - Awesome car!

From what I gather the best protection to get for the paint is a film based coating as t will resist even stone chips, which Opti Coat is unable to do. When I pick up my new car next year I'm likely going to Apply XPel or the best film based protection I can find to preserve and protect the paint.
Some apply Opti Coat on top of film based protection as more of a semi permanent/long term wax alternatively. Opti Coat apparently makes it a lot easier to keep the car clean and prevent debris from sticking to the car.
I may apply Opti Coat on top of the film based protection as some have done. From what I gather, if you go with film based protection and Opti Coat, the Opti Coat should go on top of the film.
