Im a bit surprised why folks are saying do it from inside the car. Here is another option.
When you remove the bracket (pic) you will see the window sits on simple locator blocks, you will also see there is no sealer on the inside or the edges.
Looking from the outside you will see how thick the sealer is.
Posted a pic of the footprint of your std 5 in 1 tool which is like a thick razor blade. You can also use the type tool that holds a single razor blade if desired.
From the outside your simply running flush with the glass like you were cleaning over spray or debris from said glass but in reality your just cutting through the sealer on a smooth glass surface and its thick enough that even with the 5 in 1 tool you simply compress the sealer.
It takes me about 5 minutes a window to go three passes around evenly and then it simply pushes out. Weather the dead of winter or heat of summer matters little because you simply separating the sealer from the glass.
Then when its out a simple go around with a one sided razor blade and its good.
I myself think for the side windows only its a far better way then the time and leverage against the glass used and needed unless you use the seal cutter day in day out.
Ive probably removed 20 sets this way and its always quick simple and break free.
Also if you live in a area where tint is allowed or? and its a super pac louver car you can use 1/4 smoked plexi glass of the tint you like if you wish.
I do on F-s that are not driven much because unless you do the tint yourself the tint guys usually destroy your lil plastic chrome inner trim and its hard to find them.
