Simply put, Corrosion X can be used nearly everywhere. Just think of all of the rusted or corroded screws, bolts, wires, connectors, hinges, locks, (and so on) that you run across. How many items have you found which don't work smoothly and need to be protected and lubricated? Corrosion X can reduce or eliminate these problems. Keep a can handy when you do repair jobs around the boat, car, or home.
