N1rve wroteYou probably need to watch more of the video or the first part where he talks about why he is taking perfectly good PPF off.Maybe you sent the wrong video because all I see is this guy removing PPF because his car already had imperfections?
But this is what PPF will do to swirl marks...

It wasn't paint corrected before PPF so the only way he can get the scratches out is to remove the PPF and polish it.
