  • Publication number: 20070163165
    Abstract: Surface treatment for fishing lures and sinkers is disclosed. The surface treatment can exist in a number of configurations, including holes, slots, grooves, or other details. The details have a cross section that allow them to be easily cleaned with a stick, branch, sand or other items that can be found near a lake or stream. The surface treatment allows a person to manually apply fish attractant to the outer surface of the fishing lure, and some of the fish attractant will embed into the surface treatment area providing retention of the fish attractant. In use the fish attractant will be washed from the surface treatment as the lure is moved through the water. The surface treatment can be incorporated into nearly any type of rigid or pliable fishing lure or sinker.
