3-IN-ONE RV care window and track dry lube helps keep your RV windows and doors sliding smoothly and silently. This quick-drying formula leaves a clear, protective lubricating film to reduce friction, without attracting dirt and debris into the tracks. Plus, it provides long-lasting corrosion protection against the elements, helping to prevent repairs that stall journeys and empty wallets. Safe to use on most materials, including vinyl and plastic (except clear polycarbonate and polystyrene).
