Translucent Coating For Heavy-Duty Protection Industrial Grade Cosmoline




Rust Veto 342 is a thin fluid type rust preventive that leaves an amber, translucent, waxy dry film. It protects iron and steel from rust for lengthy storage indoors and outdoors.


Numbers and lettering can be clearly seen through the film when the solvent has evaporated from it. This makes it possible to easily identify codes on items left in storage for long periods.


Those of you with a military background or who are familiar with weaponry, will recognize Rust Veto 342 as the industrial grade of our old reliable Cosmoline ® Rust Inhibitor.


Rust Veto 342 offers good protection to steel against salt spray and outdoor weathering.
