Rust Proofing

It is prevention, delay, or rusting of iron and steel objects, or the permanent protection against corrosion. Typically, the protection achieved by a process of surface finishing or treatment. Depending on mechanical wear or environmental conditions, the degradation may not be stopped completely, unless the process is periodically repeated.

How does rust form?

For rust to form, three things are needed: iron contained in metal, water and oxygen from the air. While oxygen is always present, steel does not rust when the air is dry. If steel sheds water quickly, the corrosion does not have time to form, but if metal retains moisture, it rusts. In addition, when steel is subjected to physical stress, such as sudden temperature changes, vibrations, etc., vulnerable areas can form that make iron likely to rust.

It begins as a microscopic form that is not visible to the naked eye. When it appears, it is too late to act. Also, do not forget about all the hidden areas of your car where rust can develop without you knowing: door panels and hood, rear fenders, frame, uprights and rocker panels. For these reasons, it is important to treat your car once a year to prevent rust from forming.

There are elements that can accelerate the development of corrosion:

  • Salt and calcium, which increase the conductivity of the water;
  • Air pollution and acid rain are very corrosive. As well, our air contains many more gases than it did 50 years ago, like sulfur dioxide and nitrogen oxide. This is why our cars rust more than our grandparent's vehicle did.
  • Sudden temperature changes, especially when cool or cold weather becomes warm and humid. Actually, heat expands metal, which then allows the ambient or projected humidity to embed itself more easily into steel pores. Contrary to popular belief, metal rusts in hot weather, not in winter. However, winter prepares the ground for the forming of vehicle corrosion with snow, mud, salt and calcium, and especially when wheels throw these materials violently at the under carriages of cars and trucks.
