We use a rub on deal called Fish Dope made by Punisher Jigs out of Celina TN. Not sure how the attractant aspect works, but it slicks a feather/hair jig down so it look like a dart in the water. EXTREMELY effective for winter Smallmouth, LM, and spots. Comes in garlic or shad, but I think the scent is secondary to how it effects the look/action of the jig.
