A coyote's nose is much better than a deer's. So much better that you probably WON'T be able to mask your scent if he gets downwind, no matter what you use.
There are some propanants of "misting" downwind with a brew of really stinky stuff. They say it gains them a couple of precious seconds to shoot, while the coyote is hit with sensory overload (but he still smells you too).
They are probably right, but I don't use that stuff on pain of banishment from my house.
Include "misting" in your search.
