～From the manufacturer's website～ IOS Gear Grease (for both saltwater and freshwater) This high-spec gear grease boasts excellent lubricity, class-leading load capacity, superior waterproof performance for use in saltwater, and 100% synthetic composition. It protects the main gears, the heart of the reel, from extreme cold to the scorching heat of summer and the constant exposure to wind and rain. Even with metal gears, applying IOS Gear Grease reduces friction resistance, from small reels requiring high sensitivity for lures under 1g to large reels used in saltwater that prioritize load capacity. The smooth, light rotation, often described as sensual, has captivated many users. The following is purely my personal opinion: The grease is firm and highly viscous, with a sticky impression. Due to this property, it is not suitable for use in areas of the reel other than the gears (it would become very heavy). Because of its properties, when using it, you need to apply a very small amount (about the size of a single grain of uncooked rice) to avoid making the reeling feel very heavy and hindering performance. Therefore, it may take some getting used to at first. However, once you get used to it, you can achieve a light yet smooth reeling feel, and the grease itself lasts a long time and is resistant to temperature changes, making it a very effective grease. If you want even lighter action, you can mix a small amount of your favorite oil to create an original grease of your desired consistency. You might think the amount is small, but because it's a gear-specific grease and is used in extremely thin layers, this amount is enough for several reels. For applying to the reel, a flat brush with a width of about 2mm is recommended, and an extra-fine round brush is convenient for detailed areas.
