Ardent Reel Butter Grease is a high performance synthetic lubricant designed for freshwater fishing reels and other mechanical equipment. This 100% synthetic lubricant is engineered to outlast other lubricants to protect your reel components and extend your reels lifespans. It bonds to brass, steel, and plastic on contact. Reel Butter Grease contains a rust inhibitor to prevent corrosion and a UV tracer so that the grease can be viewed under a blacklight to check when it needs to be refreshed. A patented super smooth additive keeps your reel at peak performance; regular reel maintenance is critical to high performance and longevity for any reel.
