What I find funny about this thread and others like it is that, I'd be willing to bet that alot of the same people that are recommending not to worry about the mics getting wet would post in the yard sale that their gear has been babied and kept in a smoke free environment.
If you're so confident that allowing mics (other than 4060s) is OK, would you be willing to say so in your YS listing when you're trying to sell your gear? I doubt it.
Really I don't care what anyone does with their gear, but it does bother me a little that these posts give noobs what I believe to be the wrong impression that it's OK to let your mics get soaked.
Funny, I just assume that all gear on this board has been treated this way. No need for a disclaimer IME, this is field gear not studio gear. So it's been in the field, which for probably most of us means rock concerts, inside in smoky venues (even non-smoking venues have people who will smoke), inside in venues where they use fog machines (which are basically particulate machines if you ask me), outside potentially in rainy conditions, outside in major humidity in many areas of the country, outside in a dust bowl. Babied to me means you try your best to protect your equipment despite the difficult conditions we tape in.
I don't have a problem with people who don't want to take their gear out in potentially rainy conditions, but it's a little silly to think we need disclaimers on gear sales -- again I think from the context of this board we can assume it is field gear. Why only disclaimers for rain, how about disclaimers for using mics outside in humidity (there goes sales from all of the south, and PA probably based on my recent taping excursion in Philly), or sales from places that don't have anti-smoking laws, etc, etc? Or perhaps a disclaimer that the gear was used in places where alcohol was sold/consumed, since we all know the dangers of drunks and our gear.
For my part, I tape outdoors in Colorado, which means that pretty much always you have a chance of rain (and with proper planning, your mics certainly don't get soaked even if it does rain). If you don't want to tape in the rain, you won't be taping outdoors in Colorado. But I'd still take a brief passing shower with my mics protected and under an umbrella than taping all the time where the humidity is 90+. And I've been taping in Kansas at Wakarusa where it was a serious dust bowl -- all those micro-particulates cannot be good for a mic's diaphragm.
Anyway, food for thought, but I'd say most of the places most of us tape in aren't the best for the equipment.
