I bought paint protection film from PPG when I built my car. There was a little bit of excess on the side sheets and so I used it for odd areas such as where the doors rub and on the bonnet where the stud from the door lands when the door is open. An A3 sized sheet of film should do the trick. A slight aside, I have just put TOYO R888R's on the car this weekend and I have noticed a lot more stones being thrown up onto the bonnet and the sides. On a plus side the tyres are superb and have totally changed the car, on the down side I do now have 3 tiny chips on top of the bonnet from today's drive.
