That is what I did before I even flipped it back over after putting the legs on, I laid down some sealant that I had used to great effect when I converted an old piece of furniture into a humidor (This replaces that it was just too small and I have no other furniture that I am allowed to humidify). All sealed up there around the plug so it shouldn't be an issue, I just assume that it will have some leakage around the front, I don't really trust a two door system. If I have trouble I may put some very thin stripping on but I don't think I will need it.
