Well, I' ve been skinning a bunch of skunks since land season opened. I shoot them in the head with a .22. They still spray; it must be a reflex. They' re going to stink pretty much no matter what you do. However, I find that if you wash them in a bucket of soapy water before skinning, it makes the smell milder. Also, spraying them with scent killer (my answer to all things[:-]) seems to help. Try to put them downwind of you while skinning. After you' ve done a few, you kinda get used to it, and it' s not as bad.
