3-IN-ONE RVcare Window & Track Dry Lube has a quick-drying formula that 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 plastic and vinyl (except clear polycarbonate and polystyrene).
