S2S Multi-Use spray combines a rust inhibitor, penetrant, lubricant and dielectric in one multi-use formula. It acts as a liquid de-scaler and polar bonds to metal to form a long lasting, self-healing, protective barrier from rust. One application provides a thin coating of 1-4 mils, resulting in excellent penetrant and anti-seize capabilities. Apply it directly to circuit boards and battery terminals to prevent corrosion. S2S is non-toxic, non-hazardous and environmentally friendly.
