Hi, new owner of Model 3, and about to take delivery of X. I am going to PPF both with DIY kits, but in the ordering process came across peeled or unpeeled. Can someone answer the question of the difference and why I would choose one or the other? Also for the 3, I am considering one of the less expensive options in case I mess it up and just because$$. Can someone comment on why or why not to do that? I understand yellowing in a couple of years and then I’d replace. Any help appreciated?
