To my knowledge there is nothing that will do this job long-term.

You can try Paralene - Silicone - Acrylics - Urethanes etc., but underwater?
Not in my experience.

Occasional flood? What about the connector and other uncoated items? And
what quality the rain water - acid rain?

Better to have a drain hole in the box to let it out, then you can probably
successfully use any of the above as you prefer - but keeping in mind the
pro's and con's of each.
