So, after 2 kits and 4 attempts, I finally got my Whitestone applied. I would recommend taking time with the application, making sure that everything is fully level, and doing several dry-runs before actually attempting to do it.
Also, carefully remove the top tray after dropping the screen protector, just to make sure it's correctly positioned before the first cure. That was my mistake with the first kit. The protector didn't drop down when I pulled out the tab, so I had to push it down, and it didn't fall correctly. I didn't realize until after the first cure, so I had to pry it off and couldn't use it for a 2nd attempt. I was glad I kept the extra adhesive, cleaning cloths, etc., when I got the 2nd kit, because I had problems with getting the screen to drop without bubbles under it and had to remove it twice before starting to cure it. The third attempt with the 2nd kit (and the last possible one, since it was the last of the adhesive from both kits) was mostly correct, other than being maybe a millimeter low.
I really wish that they would sell additional adhesive kits, just for clumsy people like me. I like the screen protector, but it's not worth the $90 I spent on two kits. I had so many issues with application, I doubt I'll replace it if it gets damaged, especially since you only have two attempts to apply it with each kit.
