I had my car detailed from new, even the delivery packing was left for the detailer to remove.
It has only ever been cleaned by the detailer and I plan to keep the car for 8-10 years.
I do not wash my cars.
My Grande Tour meant a large number of insect bodies/acid was left to bake onto the paintwork, some for over 8 weeks resulting in staining of the paintwork which now requires a repolish. Impact damage from stones was x2 both resulting in chips on the bonnet and one tiny chip in the windscreen.
Im already on my 2nd windscreen, that flying stone left a double groove in the bonnet paintwork that Im told should be retouched.
I was thinking of a full bonnet film cover.
Now considering bumper, wings and wing mirrors, plus those annoyingly shiney black panels behind the front windows. All depending on cost.
