So have any of your panels been corner wrapped? Especially the ones around the wheel arches and lower doors?
My authorised Xpel installer (20+ years experience) redid an original install from a different 'factory trained installer' and said what was previously installed (non wrapped version of Xpel templates) wouldn't have protected the very bits that the PPF had been purchased to protect. I asked him why the original ones might not have been offered to me, and he simply said, its more difficult to install so more expensive to do and this was reflected in the price! He did say that some bits couldn't be fully wrapped, but my installer was very selective with those - on my partial install, I think there were one (maybe two) edges each side that he didn't fully wrap - iirc the area around lower front wing as it meets the sill.
