I did a quick search and not much has been posted. All it says on the instructions is to sand the surface. Is there anything else to worry about? Also is the adhesive good that comes with it or should I get something better? I tried the fit and it seems to fit fine. There is a few raised areas where the speakers are, should I do something in those spots? It seems easy enough, but I don't want to glue it on only to find out I should have done something else.
