The last time I hunted with my SS Encore, it rained off and on for a week. My gun stayed wet or damp the whole time and yes, it rusted inside and out. Moral of the story: Oil it up, dry it out, treat it like any blued firearm and you should be fine. The SS TC uses can and does rust. I found this to be a little disappointing, but the reality is most SS that can be easily machined for barrels and action and such isn't quite as inert as you would think. Take a look at used Ruger Old Army pistols in SS sometime...you will see most have pitting from neglectful owners thinking hey, these can't rust so why clean them! "
