I had a spare bottle of loca glue from my Pixel 2XL whitetone dome kit, so I tried to use the remaining bottle on a random screen protector. It didn't turn out bad. I got some lifting on the corners, but the sides flattened out. I just needed a little more loca glue, and I would've been able to hit the corners. This screen protector was pretty long though so, i'd need enough loca glue to cover the gap, and I was just a bit short.
It hit all the sides except the corners and the glue even went to the very top despite the cutouts on the screen protector. Really wish I just had a litttle more glue
The picture is pretty bad, but now that I looked at it again in person, the glue actually hit each corner; however, there was a cap along side the corners (not actually the corners) that the loca glue didn't get through. Overall, I'll use this solution until whitedome comes out their kits.
Oh well. Interesting experiment.
