I just installed a full screen protector for my iPad 2. The back turned out pretty well. I started out with the front and it seems to have lots of bubbles left. I don't have the feeling these bubbles will disappear within the next 48 hours. So I was wondering, how long can I wait to give it another try? As in take it off and install the same protector again? Cause I have a feeling I didn't use enough solution the first try?
