Nope that's completely normal for all charger, Challenger, and 300's to look like that after tint. There's absolutely nothing you can do to change it.
Correction all after 2014 era I think was the year it changed.
I bought into it a couple years ago and felt the same. Thin, doesn't plot well, and several reported failures with it. No thanks I'll stick with global.
I'd probably say no on that. The first one pretty confident that wouldn't have been them, second one is iffy but it's pretty far away not sure why they would cut right there. A lot of people notice things after work has been done because they're looking around. Could've easily been there beforehand just not noticed.
Yeah they really suck, tight gasket around the whole window. I'm sure the front window shifts some if you roll the window down some you can grab the top edge and move it from left to right if that makes sense. However given the top edge it's a definite redo.
Front windows yes those quarter windows though can be quiet difficult to get full coverage without removing them. Unless you can see light from the inside I would be ok with those but like I said the other roll down should be removed.
Global qdp you can buy it at express and it's listed as classic charcoal 1.2. If you need something a little cheaper but will still last classic black is a great film as well.
