Fluid Film is a solvent-free rust preventive and lubricant. Its unique lanolin base penetrates and stops rust on contact. It immediately stops squeaks, providing lasting lubrication while insulating and protecting electrical connections. Safe on paints, plastics and oil resistant rubbers. Fluid Film is classified as non-toxic and non hazardous. Fluid Film's deep penetration and non-drying characteristics make it ideal for freeing up rusted, seized and corroded parts.
