I used tape to secure mine. Other people have had success with rubbing a thin coat of mineral oil on the glass and then placing the BG and sliding a credit card over it to smooth it out. Pretty much like applying tinting to a window. I am going to try this way with my 10. My problem with the BG was just trying to get it to stay flat while trying to get the tape on. Good luck!!
Yeah, no kidding about the stay flat part... I've had like 10 heavy books on the edges since yesterday, to no avail.... Well, i'll get my mom to help, lol.
