Skunk spray is a response to predation, you'll more likely spook the deer than fool them. All you can really do with odors is reduce them to the point that you seem farther away, and therefore less of a threat, than you really are. I wash my clothes in Sportwash and baking soda and hunt the wind. If a deer busts you with it's eyes and/or ears it's first response is to circle downwind to check you out with it's nose.
