For what it's worth...a few hundred miles without PPF protection is not something to worry about. I put 400 miles on my car before a PPF install, and it's immaculate. Sure, you might get a tiny chip but you're going to have to have the whole car paint corrected anyways before the PPF goes on. Any decent shop could fix that theoretical chip.
Plus, no matter how much protection you do (PPF, ceramic coating etc), there will come a day when your car gets a ding of some sort. It's inevitable. Unless you lock it in a temperature controlled glass display case and never drive it, that is ?
