No car body is immune to rust sooner or later. However, some metal products are noticeably better at dealing with this problem. Most often, the secret of "amazing stability" lies in such a rather banal thing as hot-dip galvanizing of the body. Let's take a look at the top three cars whose bodies are protected in this way during production.
Hot dip galvanizing is a special procedure during which a metal product, such as a body car, covered with zinc carbonate, which protects the metal from the damaging effects rust. Carbonate is obtained by lowering a metal product into molten and brought to a temperature of 460 degrees Celsius zinc. First, as a result of a chemical reaction, zinc oxide is formed, and then a saving carbonate is obtained from it.
1. Audi A6 C4
The first generation of the Audi A6, which was born back in 1994, is a car, frankly, not a young one. However, there are still C4s on the market in good condition. If the owner treated the car with care, then it will serve faithfully, taking into account repairs, for more than a dozen years. And thanks to the galvanizing of the body, the A6 does not have any problems with corrosion even after 10-12 years. With a careful attitude, the car can retain its original appearance for a very long time.

2. Volvo S60
The middle-class sports sedan is often undeservedly overlooked by our motorists. But in vain, because it is the body of the Volvo S60, which has survived hot-dip galvanizing and carbonate coating, that is able to break all imaginable and unimaginable records. Suffice it to say that with a more or less careful attitude to the body, the S60 will not encounter corrosion for 20-25 years. Among modern passenger cars, the car is the absolute record holder in terms of rust resistance.
3. Ford Focus
A compact American car with a long history undergoes a hot-dip galvanized body. Today, the secondary market is saturated with Ford Focus, so finding a car in acceptable condition for most motorists will not be difficult. If the "Focus" was protected by zinc carbonate, then its owner will not be able to remember corrosion for 7-9 years. Most other cars of the same class and price category, but without galvanization, begin to slowly rust after 3 years of operation.
