Those guys on TV not wearing a face mask of any kind are hunting deer in very low pressure situations. If you'll notice, they also hunt quite low to the ground w/out much cover. In high pressure areas, you'll never get away w/ that.

That being said, I've used face paint before w/ success. The only thing I don't like is removing it. Sometimes you've gotta scrub pretty hard. 90% of the time I wear my ASAT full head mask. Yes, I know......how do I feel my kisser button? Simple. I don't use one.
