The best and somehow easy way to prevent the glue would be by taking the backlight film off gently, putting a thin transparent tape on the mirror of the lcd and then applying the glue. When the glue dries using UV, take of the tape clean the mirror with isopropyl and put the backlight film back carefully. Voila, no marks and u got a clean glass replacement. Please note, that to take off the backlight you will need to unsolder the three small connections first and when putting back the backlight you have to resolder them back. Not very difficult to do so, so you can give a try. And please also note, when glue goes in between the lcd you don't have to throw it away. Just remove the backlight film and clean the mirror with isopropyl or acetone. Film costs like 5$. Just be gentle and have patience.
