Think of PPF as Saran Wrap for your car. A product like XPEL, arguably the industry benchmark, will run around $750ish if you opt to do only the areas most prone to scratches/flying debris like lower rocker panels, bumpers, front spoiler, and first 1/4 of the hood. Installers apply PPF much the same way that a color wrap is put on. If you decide to go this route for your new Z, I wouldn't use any other manufacturer's films, XPEL is the best out there.
I had a ceramic coating from Gyeon (referring to their product as "quartz" finish) applied last November. They have one of the few ceramic options available specifically made for matte finishes, so I didn't have many options to choose from. It's holding up remarkably well, enhances the color without adding any gloss, and repels water better than any wax or synthetic product I've ever used. Despite how good it is, it will NOT provide the same level of paint protection as PPF.
