YUM F2 attractant contains an ingredient that prompts it to actually penetrate into soft plastics, allowing you to “super charge” your lures before using them. Even soft plastics that don’t contain scent can be imbibed with scent to make them more attractive to bass. The day before a fishing trip, simply open the bag and spray several shots of spray into it. Reseal, and when you open the bag the next day the scent will be inside the soft plastics, and slowly release a strong scent trail as you fish.
