Abstract
Abstract A penetrating and lubricating composition consisting of a silicone lubricant dissolved in a glycol ether carrier having a very low surface tension. The glycol ether gives the composition the ability to penetrate into the cracks between two seized or corroded elements and dissolve any rust or corrosion present. The glycol ether then volitalizes leaving a coating of silicone on the parts to serve as a lubricant and prevent further corrosion.
