Who says
rust free classic parts are impossible to attain? Even your own car components can be free from rust.
Here are information, tips and guides that can help.
Rust is the common term used for iron oxide. It results from the combination
of iron and oxygen. Not all metals rust but any metal containing iron like steel
will rust when exposed to air and water. The mixture of air and water is called
oxidation. It develops reddish brown flakes all over the metal making it weak
and easy to break. The rate of rust formation can happen gradually or rapidly
depending on the material and the environment it is exposed to.
There are some factors that can affect rust formation rate. Some iron has additives
that can stop rusting.
Stainless steel has nickel, manganese and chromium components bounded with the
iron atoms which help to stop rust from forming. Since water is one of the major
cause of rust, metal car parts can be painted or coated with oil to stop oxygen
and water from coming in contact. At times, simple coating with an oil film can
do but it must be renewed regularly since it is not thick enough to protect the
metal from rust build-up.
Heat can speed up the chemical reaction between air and water that is why classic
car components constantly exposed to heat like mufflers and exhaust manifolds
gets rusty in no time at all. But they can be free from rust by regular coating
with non-rusting materials. However in places where the air is free of humidity
and in some locations where rain is not frequent like in the desserts, cars can
last longer with slowed rust formation. Classic auto parts made from thin iron
have faster rate formation rate than thick iron. Some components with steel wool
as the main component gets easily rusted that is why it is advisable to avoid
using components made from steel wool. Acid rain can also speed up the process
of rusting.
Rust free classic parts can prolong the car's life and performance. Most of the
time, the best way to treat small areas with rust is simply to grind through the
top layer of the metal until the shiny, clean part is exposed. However it is difficult
to know how deep the rust has formed making it hard to determine how long or how
far the grinding would go. If the rust has penetrated the deeper sections of the
auto part then the best solution is to cut off the affected areas to be replaced
with new steel. Yet if it is only surface rust then grinding is the most simple
and the easiest solution.
