The advice of "Once you learn how to squeegee fingers, your installs will forever be better" is 1000000% true. When I started I thought fingers meant I did something wrong and therefore I would keep trying to stretch and twist the film 100 different ways. YOUR videos specifically taught me how to squeegee fingers and that its totally normal to get them and squeegeeing over them isnt some sort of blasphemy like I thought before.
Watching videos like this I just shake my head. I use Xpel also and now way you are not getting stretch marks and silvering. Do not get me wrong, video is great but not for Xpel!
