Before lowering the glass display, I would recommend removing the tape from the edges, in order to check that the glass is seated flush against the bottom shelf of the frame. In my case, the glass got slightly out of alignment with all the lifting and lowering of the display, and I ended up with one corner being about 1 mm above the frame ledge. Not a huge error, but regrettable, as once you start to lower the display with all adhesive exposed, there is no turning back!
My EMC No. 2546 did not have a microphone hole, so I was confused at first. A different instructional video (https://vimeo.com/139364064) recommends placing the strips on the display instead. I installed the strips on the frame, but I reckon installation on the display glass might have been a better option, at least with no microphone hole to contend with.
This is a good tip!
The stickiest location on my iMac was the mid-to-lower section of the right side. There are a couple of thicker areas that needed attention from the plastic cards.
