Is there anything to coat them with to prevent mould growth?

Plenty of things -- but you wouldn't want to eat 'em after. ;-)

[Maybe the good denizens of RFC could help you, so I've added
rec.food.cooking to Newsgroups and *set followups* there. Here in the
tropics I don't have much of a problem with them during the cooler
months, but the fridge is too cold to keep them well at any time.]
