Daystar Lubrathane is specially formulated with PTFE® so that it lubricates, insulates, and penetrates. When applied during installation, it creates a durable, protective film to lubricate between your polyurethane and metal components. It virtually eliminates metal-to-metal contact, even under the most extreme conditions. Lubrathane is waterproof and corrosion-resistant and will not attract dirt or sand.
