Lock-Ease graphited lock fluid protects against sticking, rust and freezing. AGS Lock-Ease makes locks work easier year-round. Helps seal out moisture from working parts, providing maximum protection against freezing. Enters as a rapid penetrant, coating lock mechanism. The special carrier then evaporates, leaving a graphited long-wearing film. After evaporation, it will not run, even in hottest climates and won't harden at sub-zero temps. Suggested applications: all types of locks, household appliances, tools, guns, reels and other fine mechanisms.
