I installed an invisible shield on my macbook pro, and was concerned about how suceptible it may be to get water, or another liquid in the top of the lid via the apple logo? You spray the solution on the shield and then squeegee it around with some force, is it possible to get liquid inside the case via this boundary? Even something like a spray lcd cleaner or a damp cloth? How well sealed is the transition between the aluminum and the plastic of the logo?
