Ardent Reel Guard Corrosion Inhibitor uses innovative chemical engineering to inhibit corrosion on saltwater equipment by dissolving hard water minerals like sodium and potassium. By dissolving these minerals, the corrosion inhibitor significantly reduces the onset of galvanic corrosion in saltwater environments. Reel Guard is compatible with all components of reels, rod guides, and other marine equipment. Simply spray on the equipment after a long day on the water and let dry; no scrubbing or rinsing necessary as Reel Guard does the work for you. Spray bottle. Made in the USA.
