I received my Invisible Shield in the mail on Friday and went out first thing Saturday to buy an 80GB Classic. I installed the full shield on it immediately after unboxing and syncing to my computer. After several attempts, I finally got it on the way I wanted it. However, after letting it sit for 24 hours as per the instructions, there were still large and extremely noticeable bubbles and what appeared to be dust underneath. Luckily, I somehow received two of the full shields in a package (even though I only paid for one, was this a fluke or is that normal?) so I removed the first one and gave it another try with the second one. This time I was sure to use a LOT of the liquid since I've heard that works better. This time I seem to have taken care of the air-pocket/bubble issue but after several hours I went back and noticed there were some small debris trapped under the surface of the part that goes over the screen. I think I'm going to wait a couple of days on this one to see how it settles out, but are these things reusable? Like if I remove this one and just use copious amounts of the liquid on it do you think I'd be able to reapply it? I still have the first one and it's intact and in good condition just kind of dirty.

Also, does anyone know what the stuff in the spray bottle actually is? Because they don't give you very much and if it's some common household product I'd be curious.
