I've been known to warm up some mink oil over low heat til it melts, mix in cedar oil and used that concoction rubbed that into my leather goods to cover the chemical smell. (Hint: Don't use your wife's good cookin' pot for that kinda stuff) If I hunted around pine trees, I'd just use Montana Pitch Blend on my leather. It already smells like pine. I also put cedar shavings from the pet store or Wally World in the bottom of my quiver to help keep my broadheads from clanking into each other and add more cedar scent.

No matter what you do you're still gonna stink though, so best course of action is to hunt into or across the wind.
