I did put a dab of jell super glue on each of the screw heads, after they were tightened down, I then wiped them clean. Maybe a bit of RTV would be appropriate as well.
If you are trying to weatherproof an outdoor item, you will probably find that 3M 5200 marine adhesive/sealant is the best product for the job. That said, I'd be worried about temperature/humidity cycling as mentioned by others, because you will never get a 100% hermetic seal -- so some version of a weep hole and other moisture preventive measures may be in order.
