Birchwood's Barricade Rust Protection protects your firearms from rust. It rapidly drives out moisture from metal pores and deposits a transparent coating which seals the surface with a protective film. It is also an excellent penetrant for loosening rusty or frozen parts, as well as a good lubricant and an effective bore cleaner. Contains FPR to wipe off corrosive fingerprints on all your firearms.
