An entire car respray will cost anywhere from 5-20k which depends on the car, the bodyshop rates etc. Prices can vary a lot, some bodyshops over charge, some do poor jobs, finding a painter who is very good but also charges fair pricing are few and far between.
I had our Yaris rear bumper re-painted due to me scraping into it, so no damage but paint damage, it was £360 so cheaper than PPF and repaired spot on.
PPF and Bodyshops vary wildly in both pricing and quality, personally I don't see value in spending 5k to put a condom on my car.....
