No. The formula uses a quick-dry carrier that evaporates rapidly after application, leaving behind a dry graphite film. This prevents the lubricant from running or migrating to unintended surfaces, making it particularly suitable for railroad switches, hinges, and coupling components where cleanliness and precision are critical.

This lubricant is engineered for a wide range of metal-to-metal wear surfaces including railroad switches, coupling components, autotrack equipment chains and tracks, tie-down chalks and hinges, internal combustion engine components, automotive and industrial gaskets, and thread lubrication in general industrial and commercial maintenance settings.
