Hey spud;
I have not tinted the windows yet but after a bit of research I decided to just figure it out on my own,,,
the trick seems to be to move the screen all the way to the open side then carefully pull the bottom out till it isfree of the plastic track then slide the screen so that the whole bottom of the screen slides past that one deformed section of the plastic,
replacing is the exact opposite, place the screen in the top groove then using the same approximate spot pull the plastic trim down just enought to engage the screen then slide it all past that point,
I did all my screens like that and none got damaged,, (be careful though,,, this hint comes with no guarantee)
Have given some thought to cutting a small notch to make it easier but realized I wont really need to remove the screens very often
