I took three weekends to do my hood, both fenders, headlights, all four doors and front bumper. And a small strip at the rear trunk lip to protect from scratches due to loading and unloading stuff. I skipped the mirrors. Bumper should be done last when you have the most confidence and not tired. Do not try to rush it. I worked only on the weekends and because I had to use the car, would wash, prep and clay bar the surfaces each time.
I won't claim it was perfect. Some creases at the bumper and a couple of small odd clay specks that showed up the day after. You really need good light in the garage, clean the garage and spray a fine mist of water to keep the dust down.
I did this in mid-late 2021 and nothing has lifted. But the bumper and hood show evidence of sharp things impacting and cutting the PPF but not the paint below. Also someone tried to scratch or key one of my doors. I was able to buff out the scratch on the ppf. It's a worthwhile investment in time and money. I would do this again the next time I buy a new car and hopefully will be better at it.
