Hello. I plan to use the Bodyguardz to protect my new MBP 17". I understand that to put the films on the MBP perfectly, it is recommended that one needs to spray lots of solution on the films. 1. Won't the machine be damaged if the solution get into the machine? I am particularly worry about the areas on the speakers. There are lots of holes. 2. If I later decide to remove the films, will there be residues? 3. Does the solution affect the case in a negative way? I heard that the solution is like water mixed with shampoo. Wonder if this will discolor or create marks on the case. 4. Will covering the speakers affect the volume and air circulation? Thanks.
