Zep 45 Penetrating Lubricant dramatically reduces friction and provides a continuous wear-resistant film that lubricates and protects all moving parts. This high-performance formula penetrates deeply into tight spaces, breaking through rust, dirt, and grime to free up stuck bolts, nuts, screws, and other metal components. The lubricant spray loosens frozen parts due to wear or corrosive action. Zep 45 is ideal for use in automotive, industrial, and mechanical applications, delivering reliable results when you need them most.
