Hello! :wink:
We have a great step by step instruction along with an installation card to squeeze out any airbubbles that may be trapped when applying the screen protector. Air bubbles may occur when you apply the protector, however removing it is a simple task with the installation card. And to answer your second question, no...JAVOedge's screen protector will not curl up if you reposition or reuse it.
Have a great new year!
Best,
Kelly
