One weird thing about i-glue:
- When you first get it, it has a terrible hold. Lasts like 1 or 2 days then it lifts like crazy...
- After 3 or 4 weeks, the i-glue improves, and gives longer and longer holds. You can now tack it back down and it will hold again...
- After 1 year it will give 7+ days (if the bottle lasts this long)

My thoery on this; exposure to air makes the i-glue thicker. So now, I just leave the bottle open for a night and get it to thicken a bit. Because this stuff is actually terrible when you first get it, so beware!!!
