HALO® WET chain lubricant is engineered for unparalleled drivetrain performance in both clean/dry and wet conditions. Three elite grade ingredients deliver superior results: 
Gas-To-Liquid (GTL) is a hydrodynamic fluid film synthesized from natural gas. Its unique molecular structure minimizes drivetrain noise, dramatically reduces friction, repels water, and maintains viscosity in extreme temperatures. 
Spherical Tungsten features a proprietary hollow core to help reduce vibrational friction caused by high torque pedaling. Micron-size and spherical shape helps reduce sliding friction by creating a rolling effect on the surface of the chain. 
Ceramic boron nitride platelets cover the chain to form a protective non-stick coating. This ceramic coating works synergistically with spherical tungsten to substantially reduce wear and help extend the life of drivetrain components.

HALO® lubricants are applied with Finish Line’s new patent pending Smart Luber™. The Smart Luber™ represents a paradigm shift in the way bicycle lubricants are delivered onto a chain. It ensures no link is missed, no mess is made, no lubricant is wasted, and no time is lost when lubricating a chain for maximum performance.

Instructions: 

Shake vigorously and apply to a clean, dry chain. Apply a second coat for peak performance and longer relubrication intervals.
