You use it on stink bait tubes, the hooks with springs, or looper rigs. You just push whatever stink bait holder you choose deep into the stink bait and thenpull it out slowly. When the stink bait holder is pulled out there should be a generous helping on the hook. At that point cast it pout just like you would liver or shad or any other cut bait.
Personally while no the best Ihave tried I pretty much always carry a jar of hog wild somewhere in my pack. I have caught several fish on it over the last summer, the biggest being about a 5 lb channel.
