I installed some a couple weeks ago on a 2019 F350. It's interesting to work with due to the thickness. My take away. I used a lower heat to shrink in than tint, which counters what they told me, but the first attempt I ended up burning a lot of spots. Slow and steady was the key. I used a glove and in some places a hard card with a towel and no scratching, though on the first attempt since it was already going in the trash, I tried some spots and straight hard card will put some scratches on it. It is very clear to look though, and I talked to my friend I did it for and you don't notice it's there. He has lane departure and is a habitual car wash user, so I figured he would be a good tester, not to mention it was his 3rd windshield on a 2019. I'm going to likely start offering it here since we replace a lot of Subaru and KIA windshields that seem prone to cracking.
