I have my Gen3 headlights and entire truck wrapped. Have had no issues. Love me some PPF
Same here on my Gen2 - whole truck. I have been using PPF on headlights on other vehicles for 15 years. Not only is it never an issue, but it protects the lens from hazing / yellowing. Even when I buy an older car to fix up and it has hazed headlights, I buff out the headlight, install PPF, and problem solved.
A big fan of PPF on headlights, as you can tell.
