I just got a Moshi Palmguard for my Macbook. I first washed the surface with water, and then I peeled the palmguard off the cardboard. I stuck it on, but it doesn't seem to stick. And it doesn't seem to have a backing to pull off. It looks like an adhesive. Can anyone tell me how to install this, based on their own experience? The instructions included are the same as the following link: http://www.moshimonde.com/palmguard.htm and yet I can't make sense out of step #2. It just isn't sticking.
