XPEL since new on my white 2015 (entire car). Never used automated car wash and only park in covered garage at work and home. 148k miles. Only use spray cleaner and spray wax with microfiber towels to clean/maintain. Super easy to do and can use as much force/friction as you want on the PPF without worry.
That being said, if I were to do it all over, I would only put it on the hood, front bumper, and front fenders. And have mud flaps to protect the rear doors and rear fenders, which catch a lot of flung road debris. The rest of the panels haven't been vulnerable to much, so I wouldn't bother covering them in the future. The issue I am dealing with now is this -- there are plenty of minor gouges that went through the XPEL in the vulnerable areas. They trap dirt and cannot be cleaned. Do I replace the PPF? Live with it? Take it off and stop worrying? The cost of replacement versus the current value of the car starts to become more of a factor the older the car is.
