This is your best tool when it comes to cleaning and lubricating a flat and narrow mast track. These types of tracks use Sliders to raise and lower the Main Sail. Your track has one of these rectangular channels which vary in width, but a round barrel or slug wont fit inside. The highly absorbent foam will blow your mind, when you see how much lubrication it holds. Soak it for ten minutes and you're all set to hoist it up and down. Slick and ready to sail.
