I knew that would get some attention. I didn't want to highjack the thread a few posts down.

Is it possible (or advised) to use one of the (many) spray-on applications on the shell of a down bag to at least make it a little water resistant? Specifically I am speaking of warding off condensation, frost and the drips from opening the rain fly, etc...not exactly waterproofing. I've never owned a down bag, and I'm ignorant.
