Appears that Sailkote is no longer available in 14-16oz spray cans; now its available in 8oz spray only for approximately $13. Evidently, Sailkote is based on Dupont's Krytox, a high performance lubricant. I have used it over the years and its definitely good stuff for lubricating sheaves, turning blocks, etc. on my in mast roller furling system; however, I am always evaluating and looking for substitute products that provide comparable performance at less cost. Dupont has a product, Dupont Dry Film Lubricant; Its colorless, waterproof, and dry similar to Sailkote. There is no mention that the Dry Film Lubricant contains Krytox as does Sailkote. Wondering if any of you have tried this product in place of Sailkote. A 14 oz can sells for $10.00. At approximately half the cost of Sailkote, I am going to give it a try.
