Where oxygen is an
essential for human beings without which life is impossible, there at the same
time it is the enemy of some of the objects. Its hostility is greatest for the
metals like iron with which, when it reacts, forms rust. The rust corrodes the
metals gradually and damages them ultimately. For the same reason, rust is
supposed to be one of the greatest foes of automobiles, which keeps trying to
harm the auto body openly or furtively. Whenever your car gets any scratch or
cut that exposes the metallic surface, the chances of the rust formation
increase to a large extent. Although, the auto body is covered with the layer
of paint finish but if the cut is severe, it can penetrate the coatings
enabling the oxygen to access the bare metallic surface. The deceiving
propagation of rust remains hidden until the irregularities are observed over
the paint that has a tendency to scrape. It is important to repair the rust
issues of your car in time so that its expansion can be halted and prevented
the corrosion to take place in the long run.
To begin with,
identify all the areas of your car, which are affected by corrosion. Wherever,
the rust is visible, grind it away using a grinder. Not only the rust, but also
remove the paint surrounding the rusted area to reveal the metallic surface of
the auto body. The grinding should be done in a way that about three inches
portion around the rusted area is exposed. The process of grinding is necessary
because if the paint is done directly over the rust, the process of corrosion
continues eating away the metal of the auto body.
Once all the rust is
removed, use body filler to apply over the previously rusted regions. The
coating of body filler should be sufficiently thick, and it should completely
fill all the depressions caused by rust. Before going further, leave the filler
for some time until it is fully dried.
When the filler has
been applied, you may notice the presence of a lot of unevenness on the
application area. To make the surface even, it must be sanded by a sanding
block and using a sand paper of size 36 grit. The next covering is to be done
using putty on the filler coating. When it has got dried, sand it with a
sanding block which has been wrapped by a sandpaper of grit 80. The area which
is not required to be painted should be covered with paper and masking tape.
Squirt the
automotive primer over the whole area comprising the naked metal surface and
then allow it to dry. Repeat the process three times to get three layers of
primer. Again perform the sanding of the topmost primer layer with sanding
block technique. Use 120 grit papers this time. To hide the primer layer, apply
thin coats of auto body paints. There should be four layers of the paint and
each layer must be given enough time for drying. When the paint is dried out completely,
shower another four coats of a clear coat to give a shiny appearance to the
auto body panel.
