What you see is what you get. That may be true to some but not in the case of your car's rocker panels. The rocker panel is the underneath extension of the vehicle's body panel usually found under the doors. Rocker panels are covered with rock proof protectant to prevent rust and corrosion but it may not last for a long time because of the everyday exposure to wear and tear which can cause the polish to break off. As a metal component, the rocker panel is not an exemption to rust and corrosion which is often the cause of downfall of tough and world-class car makes and auto parts.
Rust is the result of iron oxidation together with water molecules that becomes attached with iron particles to produce Fe203. There are several factors that affect the rate of rocker panel rusting. Rocker panels made up of iron have added components that can prevent rusting. Nickel and chromium are the components making up stainless steel metals which provide stronger resistance against rust damage. Coating or painting with oil can also avoid the malady that rust can cause. The oil serves as the barrier that prevents oxygen and water contact and thus slows down rust formation.
The environment is also a major factor in rust formation on the vehicle's rocker panel. Rocker panels don't rust over long periods of time in places with dry air while locations that are constantly visited with rain may lead to easy rust formation. The thickness of the rocker panel also affects rust formation rate. Thick rocker panels may take a longer time for the rust to get through while rocker panels made from thin metal sheets can easily get rust holes.
In case the rocker panel is infested with rust and there is nothing that can be done, then replacement is the only choice left. The market offers loads of rocker panel replacements that can give the same or even better performance as compared with old factory panels. A Toyota rocker panel can be a good choice. Rocker panels from Toyota are made up of authentic quality metals equipped with components for longer lasting protection against the destructive rust.
