Hey guys... there's one critical step that's missing here. Before doing Step 18, you have to make sure the iSight camera is in the right place. It's 'floating' inside the computer housing and has to be positioned just right for the glass to close/seal properly with the frame. I followed all of these steps but the glass would not seal around the camera, leaving a 1/8" gap there and distortion on the LCD when powered on. I had to re-order the strips and do the process over again. While doing a 'dry run', I realized the camera was the culprit and was able to hold it in position with a paper clip which allowed for the glass to adhere properly on the 2nd try.
