Rust – The Cancer of Cars

Cars and rust seem to go together. But how does it start? Where does it come from?

Why can’t car manufacturers do something about rust?

The answer is – THEY DO! Metal parts are either painted or covered with a non-corroding metal. The trouble is, these protective coatings start to deteriorate soon after a car leaves the assembly line. Cars are exposed to sunlight, moisture, air pollution, sand, and chemicals – all of which shorten the life of the protective coatings.


Rust is formed by the union of oxygen in the air with iron or steel by a process called oxidation.

Moisture is an important agent in producing the change. Anywhere you find unprotected metal parts, oxygen, and moisture, you can – and probably will have – rust, but the rust may not always be evident.

Rust can form inside hollow metal parts, below metal surfaces, and inside hidden seams.

If rust can start anywhere, including inside parts, then how can a body repairman detect all the rusted areas?

He can’t! He doesn’t have x-ray vision, so it’s impossible for him to detect rust that has started in hidden places. As vehicles are taken apart for repairs, the rust will only be detected when we can access those hidden areas.

So what can you do about preventing rust?

Take care of your car!

Dirt holds moisture – a dangerous rust agent. Wash your car thoroughly… including those “hard to reach spots” like door-jambs, wheel wells, etc. Those are the areas where rust is likely to start. Only by properly maintaining your vehicle, inside and out, will you be able to spot rust or prevent it from happening.

If you see rust forming, or if you have a severely rusted section, it may be necessary to replace the rusted section with new material. The sooner your fix it, the better. Painting over a rusted area does not fix the problem, and if anything, will only accelerate the problem.

If you have a rusty spot or section of your car, schedule an appointment with us to address the problem. We’ll educate you as to what needs to be repaired or replaced to properly take care of the situation and prevent it from getting worse.
