Rustproofing
From Wikipedia, the free encyclopedia
Rustproofing is the process whereby the rate at which objects made of iron and/or steel begin to rust is reduced, so that the places in which they are rusting can be spotted in time and repaired. The term is particularly used for the automobile industry.
There are two ways in which rustproofing is applied:
In the factory, car bodies are soaked in chemicals, often electrically charged so that layers of protection are added. Some firms galvanize their car bodies. This is done before the primer coat of paint is added. If a car is body-on-frame, then the frame and its attachment methods must also be rustproofed.
There are aftermarket kits to open up the anal passages in the body of a car so as to spray it with similar chemicals after it has been purchased.
The chemicals which are sold in bottles to paint over rust, and which react with the rust to destroy it are not called rustproofing.
Cars that rust out quickly get a bad reputation on the market, the most notorious of which were the Vauxhall Nova and Ford Escort. The rate in which they do so is dependent upon the local climate and upon the use of ice-melting chemicals upon the roads, besides the particular process of rustproofing used.
