tonedeaf--
I really wish that you would stop using the word "soaked". I haven't read one post so far that even REMOTELY advocates, encourages, or suggests that allowing mics to get "soaked" is okay and advisable. All of us are responding to the OP's question: "Any tips/advice about taping in the rain would be very much appreciated."
That you have decided never to tape in the rain is great. I believe that everyone can agree that leaving your mics home on wet days is certainly safer than bringing them out. But you seem far too inclined to assume that there is absolutely no way whatsoever you can bring mics out in the rain and have them stay dry. It seems a little silly to me, honestly. Certainly you could, if you wanted to, bring a cotton ball with you on a rainy stroll through town and, with proper preparation, not worry about it getting wet. Granted mics and recording devices do have a few more considerations than cotton balls, but it is still agonizingly inaccurate to assume that there is no way whatsoever to bring them out without having them "soaked" or even remotely damp. Really, without having them get even slightly wet in any capacity.
Without giving away too much (since we're still talking stealth, here), I wear the mics with condoms, tied off with elastic bungee type string, about 1 inch below a wide brim waterproof hat (
Driza-Bone-- name says it all). From there cables run directly into an inside pocket in a very water proof coat, which has my recording gear all in bags-- two bags each-- taped and sealed.
Everything gets rigorously hand dried and allowed to air dry before any waterproofing is removed.
To presume that it is impossible to keep something dry in the rain is ridiculous, and even more unfair is to insist on using the word "soaked." I would be willing to bet that my mics stay absolutely 110% bone dry during this sort of situation. Again, I'd never encourage anyone to do something that they're uncomfortable with with their mics, but to the OP's request for information about how to accomplish his / her goal, I feel that the best advise that could be given a) affirms that taping in the rain is serious and far more dangerous than taping in a dry environment, and b) goes on to explain what steps are necessary to see to it that your gear stays safe, should you decide to move ahead and tape.
