New vehicles are only designed to prevent corrosion from everyday driving on our roads, but they cannot stop rust from driving on the beach. If you live in Brisbane, Queensland and you own a four-wheel drive, chances are you take it on the beach. Whether you go to Stradbroke island, Fraser, or Moreton island your vehicle is being exposed to harsh salt from the ocean. The salt and sand mixture sticks to the metal underneath the vehicle and inside all the cavities. If not immediately removed it will start to corrode the painted surface, then begin rusting into the metal. A rusted vehicle can be dangerous as the structural rigidity is compromised resulting is less safety. Handling will also be affected as a more rigid chassis improves handling. Single layer bitumen rustproofing is a cheaper more economical way to rustproof your car. It provides basic protection against light amounts of corrosion. A twin layer rustproofing system is best for mine-spec level corrosion resistance. Clear layer primer followed by a bitumen tar layer is the best way to fully rust proof your vehicle and maintain high re-sale value. Rust proofing the engine bay and inside the chassis rails are also the only way to guarantee a quality rust proofing job. Not only is the vehicle aesthetically pleasing with it is classic black look but also easier to wash sand out of. Rust proofing adds a slight layer of sound deadening and seals the undercarriage preventing red dirt ingress. If you have ever had to deal with red dirt in all the cracks of your vehicle, getting it sealed with a chemical rustproofing is the way to go. Make sure the rust proofing you buy has a warranty. Warranties protect you from faulty or untested products in the marketplace. Trust tried and tested warranted protection systems to ensure you are not left out of pocket with a big bill. Make sure when you are travelling around Australia you are protected with a quality chemical rust proofing system. Trust off road specialists that live and drive within Brisbane that know the best quality products and services to provide your vehicle. Rustproofing also have anti stone chip properties, not only do they protect from salt corrosion but also resist stone chips. Items most likely to suffer from stone chip damage on the underside of a vehicle are the suspension components. Suspension components suffering major stone chip damage will expose their metal as the paint will be damaged and flake off. Once the metal is exposed corrosion from salt will begin and then costly replacements will be required for expensive suspension components. Other underbody items that could be damaged from stone chips would be the underbody protection tray, tow hooks and differentials. Make sure your vehicle is stone chip safe and do not allow removed paint to become rusted metal. Even if stone chips do not occur on underbody painted surfaces, regular exposure to salt water will strip paint removing its basic level of protection from rust.
When drying time is an issue resin-based underbody rust sealant are the solution. It is ideal for quickly and effectively rustproofing vehicles with a drying time of 3 days as opposed to 3 weeks. It can be applied over rusted surfaces if the rust is not flaking off the vehicle such as light surface rust. It will neutralize and provide prolonged protection on surface rusted metal. It contains a blend of fast curing resins with power rust penetrating, anti-corrosive agents which will encapsulate the corrosion preventing moisture ingression when cured. It dies to a black semi-gloss finish and is hard wearing for heavy duty use.
Rust is iron oxide, a reddish-brown oxide caused by the reaction of iron and oxygen with a catalyst such as water or air moisture. With enough time any iron mass can completely convert to rust. Iron does not have passivational protection to underlying iron which is why rust on a vehicles chassis can cause holes and eventually break. Other metals such as copper do have passivation which is a type of corrosion that protects the underlying copper from further corrosion. There are several forms of rust that are distinguishable through visual inspection. Rebar in underwater pillars causes green rust. Rust is generally thought of as a negative aspect to iron however, stable rust can have passivation effects. Low relative humidity creates a stable layer. Cor-ten is a special iron alloy that rusts but will retain structural integrity. Rust really is the general name for complex oxides and hydroxides of iron which are exposed to moisture and oxygen for long periods of time. The term rust describes a few processes to iron such as the ios of electrons from the metal which can be prevents with electronic rust proofing. The largest aggressor for iron causing rust is water, their molecules can penetrate microscopic pits and cracks in exposed metal. Hydrogen atoms combine with other elements in the metal and form acids which expose the metal further by increasing the size of the pits and cracks. Chloride atoms in salt water will hasten corrosion once inside the metal and oxygen molecules will combine with metallic atoms to form oxide compounds, weakening the metal making it brittle. Galvanizing metals by coating them with a protective layer of zinc through hot dipping or electroplating is a cheap solution. Rust can be controlled with paint, wax, lacquer, or chemical rustproofing. Covering steel with concrete is technically a rustproofing solution. Oils and greases can also provide a temporary rust proofing solution but cannot compete with permanent chemical rust proofing systems such as Endrust. If you could control the moisture around your car rust could be avoided entirely on your car. Driving through salt and water will cause rust but even driving normally will eventually cause rust from Brisbane’s humid environment. Unlike in Europe where the roads are salted our vehicles will not have accelerated rust to the same degree, our vehicles will still rust naturally and only have thin paint from the manufacturer as protection.
