Thats an interesting thread you found by doing a search, but it still leaves more questions than answers unfortunantly.So with a simple search:
For the most part, wet molts are rare and not documented very well because of this reason, not to mention there really isn't a lot of information relating to the cause of wet molts to begin with.
It doesn't appear any of the individuals who suffer wet molts to this degree survive.
Ryan, that's really sad and I'm sorry you had to go through that. Sorry for your little P. metallica as well, although now he is much better off.
