Description Spike-It UV Glow Aerosol Can 142ml For use on crank baits, jigs, spoons, and soft plastic lures | 5 oz. aerosol can Fish and humans see things a whole lot differently than each other. As anglers, we tend to choose lure colors based on how we see them instead of how fish do. Research has shown that predator fish are attracted to UV light and use it to locate their prey. UV light penetrates water much deeper, allowing fish to see their prey from greater distances. UV-Glo reflects UV light making your lure easily seen by hungry fish! UV-Glo comes in 3 applications; aerosol, marker and dip. The marker and dip are for soft plastic lures only. The aerosol can be used on hard and soft lures.
