Rust proofing a vehicle of any make or size is important to sustain the longevity of the vehicles mechanics and body work. Rust is formed by a combination of water, air and steel, a process in which the water and air break down the composition of the steel. Rust can form on the metal parts of a car, particularly in snowy climates when salt is used to deice roads in winter. Salt also contributes to rust formation.
Rust can begin to spread in areas of the car exterior where paint has been chipped away exposing the steel underneath. It can also start from inside the car body and spread out. Rust proofing is when a petroleum or wax based coating, is applied with special equipment to the inside sections of the car body, such as the inside of door panels and fenders, as well as to the exterior.
DIY rust proofing kits are available to apply rust proofing compounds both to external surfaces and inside enclosed sections, through either existing or specially drilled holes. The compounds are usually wax-based and applied by pressure spray. Loose or thick rust must be removed before an anti-rust wax is used. Aftermarket underbody
rust proofing waxes can also be applied, which provide a tough elastic waxy protective coating giving a high degree of protection. Rust proofing waxes are particularly useful in high-impact areas like wheel arches.
All metal on new cars, vans and trucks, receive a factory rust proofing treatment before being sold, but despite this, they can begin to show important signs of rust after only 5 to 8 years. For vehicle owners who intend keeping their car for more than three years should consider a rust proofing treatment. Not only will the car look better, but over a 7 to 8 year span, it could prevent the replacement of parts such as brake lines, electrical connectors and of certain body panels such as lower door seams.
Regardless of whether a car has been rust proofed, the onset of rust can be minimized. Washing vehicles at least once a month throughout the year and within a week following a snowfall or icy period when roads have been heavily gritted can reduce the onset of rust. Periodical washing of the undercarriage is also a good way to protect from corrosion. Visit a manual car wash on a monthly basis and spray the underside of your car and inside the wheel wells too. A build up of dirt can hold moisture against your car's undercarriage and promote rust. Keeping it clean under there will allow surfaces to dry quicker making it less susceptible to oxidation.
