This penetrating oil spray is a versatile lubricant and rust-busting formula designed to free stuck, seized, or corroded parts fast. Special additives work to loosen rust and corrosion while penetrating deep into subsurface areas to reach threads and joints that other products can’t. Once applied, it reduces friction, prevents future rust formation, and leaves behind a light lubricating layer to keep components moving smoothly. Ideal for freeing bolts, nuts, hinges, and other metal parts, it’s a must-have for automotive, industrial, marine, and household maintenance. Each case contains 12 convenient 10oz cans, making it perfect for professional shops, fleet maintenance, or keeping on hand for regular repairs.
