Lubricant – emergency repair. Shock freezing (-40C). Releases rusted, corroded and seized components. Wicks directly into the rust by capillary action.LOCTITE LB 8040 is a special mineral oil designed to free rusted, corroded and seized parts.

This allows the lubricating ingredients to wick directly into the rust by capillary action. The product leaves a thin film on the released parts that lubricates and prevents rust.
