The buyer will be pretty sorry when he peels it away after 5 years to find that the clearcoat is also peeling with it. lol
this coating is good for about 4 months after which it should be removed. I'll tell you a little story on this step.
there are 3 premium german manufacturers - you already know, All make cars and park them outside ready to ship/roll. Acid rain, industrial fall out, bird droppings damage the painted finish.
so BMW - went out and made some shaded areas and also applied this plastic to their cars horizontal surfaces for the cars parked fully exposed, Audi went all cuckoo and fully enveloped the cars, Mercedes Benz being their "aangan tairha" situation send small aircraft in the sky to change the weather of the area where they park the cars. lol
Of all the solutions they chose the most obtuse one.
