I've seen a lot of people having some trouble's with the mercedes E-class BREAK'S triangle ...its this MF I'm talking about

Most cars of this type I see driving around are only tinted to where the rubber starts ...The others have removed it before installing . the problem most people have with this that when installed in place ( without any removal) there mostly is at least 1 of these motherf@cking airbubbles is in the corner , and no tool that can reach it and can give enough pressure at the top to push it out ..
So I use the CONQEURER and flip over the top like so..

So after trimming the rubber , gave it all a bit of heat to prevent the film gets pulled out when sliding in and out the adapted tool to get rid of this unreachable bubble ..
...I'm not saying this is THE salution but A salution ....well it saved my day a few times
On the other side I'm very interested how you guys pull it off and/or what tool you use to do it
