Overview

Sta-Lube SL3121 is a blue, tacky grease engineered for demanding water exposure. Built on an aluminum complex base and a highly refined oil, it forms a cohesive film that clings to metal surfaces. A polymer additive boosts adhesion and helps minimize water wash-out, making it a practical option for tough, wet environments.

The distinctive blue color and thick, sticky texture aid visual inspection, helping you see where lubrication has been applied. In real-world use, this type of film can stay in place through splashes, rain, or spray, supporting ongoing protection for moving parts.

Key benefits

  • Blue, tacky film that adheres to metal surfaces
  • Polymer-enhanced adhesion with non-blend characteristics
  • Strong resistance to water wash-out under harsh conditions
  • Designed for marine gear, trailers, and rugged outdoor equipment

Real-world applications

  • Boat trailers and marine equipment exposed to spray and splashes
  • 4WD components, axles, and chassis in wet or salty environments
  • Maintenance tasks where durable, long-lasting lubrication is helpful

How it works and usage tips

The grease combines an aluminum complex formulation with a refined base oil to form a protective film on metal surfaces. To apply, clean the area, apply a thin, even layer, and work it into moving parts as needed. Store in a cool place to maintain consistency and avoid hardening.

What to know before use

  • 14 oz. tub packaging for convenient DIY or professional use
  • Blue color provides quick visual confirmation during re-lubing
  • Suitable for applications where splash and spray are common
