Step #3 is the first of our lubricants. Originally, we intended this product for the traditional shooter who preferred oil as a lubricant for their weapons. For this purpose, it is an outstanding performer. However there are other properties to #3 that make it useful for every shooter: it is a moisture displacer; it is a rust buster; it protects actions, chambers and barrels for short-term storage. Whether you want water to bead up on your weapons, you want to remove surface rust or loosen a frozen action, or you want to put your guns away till next season, #3 will do the job.
