Rust Proofing Methods
Rust can affect your tools, guns and vehicles. (rust 2 image by Stanislav Halcin from

Your cars, tools, guns, lawn furniture, iron artwork and any other possession made of iron or steel will rust when exposed to oxygen and moisture. Rust not only creates an eye sore on lawn furniture and art work, but can also inhibit your car, tools, or guns from functioning properly. But there are methods of rust proofing your iron and steel possessions.


To prevent rust build-up or to stop iron or steel from corroding further, you can have the metal dipped in liquidised zinc. This very thin layer of zinc protects the metal from moisture and oxygen. The automobile manufacturers now galvanise the body panels of cars to prevent rust. While zinc does not rust, it will, however, corrode over time so galvanisation will not protect your iron or steel forever. The lifespan of the galvanisation depends on the thickness of the zinc. Galvanising is an inexpensive rust proofing method.


Used mostly on guns, you can rust proof steel items by dipping them into a mixture of boiling water, potassium nitrate and sodium hydroxide, or boiling water, nitrates and chromates. This causes a chemical reaction that results the prevention of rust. This process is called hot bluing. You can also use the cold bluing method to rust proof your steel. There are countless different chemicals---metallic salt, strong acids, chlorides and others---and formulas for cold bluing steel. Dip a brush into the chemicals, submerge the steel into boiling water, then scrub the metal with the brush. This turns the metal blue---hence the name---and protects it against rust. However, you will still need to oil your gun.

Primer and Rust Resistant Paint

To prevent your metal artwork or lawn furniture from rusting, paint it first with a primer, then a rust resistant paint. These paints act as a buffer between the metal and the outside elements that cause rust. Rust resistant paint can be found in paint, hardware and building supply stores.

Shushing Oil

Though waxed based shushing oil is commonly used on vehicles and ships, you can also use it on other iron or steel items such as artwork. Considered a nondrying oil, shushing oil adheres to metal, protecting it against rusting and corrosion.

Cling Wrap

You can also prevent moisture and oxygen from oxidising and rusting your smaller metal items---like guns or figurines---by wrapping them in cling wrap or enclosing them in a glass case.


Keep your metal out of climates or environments that contribute to rusting, such as near ocean swhich are high in salinity or regions with high humidity.
