We get to read most of the articles and studies about protecting
vehicles against rust and log into many discussion groups found on
automotive forums about the subject and it ceases to amaze us how
different the opinions are on the topic. We have compiled
information for you, the consumer, so you can make up your own
mind. There are traditional chemical applications and newer
environmentally friendly electronic rust protection modules that
have become very popular to choose from.
Rust is nature’s way of returning a man-made product such as steel
back to its natural state — iron. Steel contains iron and when
exposed to air and moisture, rust will occur. The chemical process
that occurs is called oxidation. Where’s the
proof? Leave the cover off your barbeque for a couple of
seasons left exposed to the environment and you’ll see the
evidence! Even stainless steel barbeques have regular steel used in
the support frames and that’s where you’ll find the brown stuff
start to form. The steel that is used in vehicles is galvanized
which does provide protection. Galvanizing is a process whereby
steel is dipped into a liquid metal (zinc), thus forming a barrier
between the steel, moisture and air. Every time a piece of sheet
metal is cut or welded in the manufacturing process, the
galvanizing protection is lost thus creating a rust-prone area.
These areas are precisely where rust starts to form on a vehicle in
its 3rd or 5th year on-ward. Where’s the
proof? Open the sliding doors of some 3 to 5 year old
mini-vans and you’ll see the evidence! Also, consider the amount of
bombardment the under-body of a vehicle endures. Stones and gravel
are kicked up hacking away the galvanizing protection from the
factory leaving bare metal exposed. Can you imagine how the under
body can’t begin to rust?
Most manufacturers’ corrosion warranties were written by highly
paid lawyers. When you read the fine print, you’ll discover that
the corrosion warranty is really only a perforation warranty
covering rust from the inside of a painted body panel through to
the outside caused by defective parts or poor workmanship.
Specifically not covered is any rust caused by a scratch, ding or
dent where bare metal is exposed to the environment. Any rust
caused by industrial fallout, acid rain or ROAD SALT is
specifically not covered. Also not covered is the complete
under-body, wheel wells, suspension area, braking and steering
systems, the engine bay and trunk. Where’s the proof? Read your
manufacturer’s warranty and you’ll be surprised.
Many experts suggest against protecting your vehicle if you’re not
going to keep it a long time as you won’t realize the benefit from
the investment. The true cost of ownership is what you pay for a
vehicle plus the maintenance and repairs less what you’ll receive
for your vehicle when you trade or sell your vehicle privately.
When a consumer is considering purchasing a used vehicle, one of
the first questions asked is if the vehicle was rust-proofed. Why?
They want to know if the original owner protected the vehicle and
if they didn’t, rust could have started to form in hidden areas;
when it starts, it’s like a malignant cancer in the vehicle.
Where’s the proof? Consider the resale value of a home that has had
thermal aluminum or vinyl windows installed, extra insulation
materials or treatments applied or vinyl fencing installed for
example. These homes traditionally will sell for more and much
quicker because the purchaser feels more confident because the
original owner invested in the home with materials and treatments
that will keep the home looking new for years to come.
Many experts claim that applying an oil spray every year or two is
an excellent investment and the best way to protect your vehicle.
While oil spraying will provide some protection, the best time to
apply any protection is when the vehicle is brand new with no dirt
or grime accumulation. If you drive to your local oil spray
facility, the installer likely spays the oil on top of whatever
dirt or grime has accumulated. Any accumulation of dirt and salt is
therefore trapped causing a rust-prone area. The rust that forms
from this process is called poultice rust. Where’s the proof? Does
the installer at the oil spray facility pressure wash the under
body of your vehicle and let it dry before spaying on the oil? Why
do most automotive dealerships not offer oil spraying as a solution
to protect vehicles against rust? The answer is quite simple; it’s
not the best solution for their customers.
Oiling a vehicle would involve less labour and the material costs
would be significantly less expensive if profit was their only
Many automobile manufacturers’ brochures and advisories indicate
that further protecting your vehicle with rust protection
applications is not necessary under the corrosion warranty. Those
high paid lawyers really do earn their wage! The corrosion warranty
only applies to the painted body panels and the warranty covers
rust that is caused by a perforation. The warranty does not apply
to the other components and areas of the vehicle that are not
covered and so the brochures or advisories refers only to
perforation on a painted body panel. Where’s the proof? Read the
brochures, advisories and the warranty booklet and you’ll see how
it instils false confidence.
Apart from protecting a vehicle from rust corrosion, undercoating a
vehicle creates a sound guard that will reduce road noise. Where’s
the proof? If you tossed some marbles into an empty paint can and
shook it, they would make a rather loud sound. Toss some marbles
into an empty paint can that was treated with some rust protection
and the noise reduction is quite noticeable.
Electronic and Environmentally Friendly Solutions:
An electronic rust module installed on a vehicle
inhibits rust from occurring by thwarting the chemical reaction of
oxidation. Whenever the protective coat of the paint is broken, the
underlying sheet metal is exposed starting the corrosion process.
Conventional chemical applications protects the vehicle from the
window line down but now, electronic rust modules protect the
entire vehicle up to the roof.
Electronic Rust Protection either supplies an overabundance of free
flowing electrons onto the exposed sheet metal inhibiting the
oxidation process or combines strategically placed positively
charged anodes to draw the current away from exposed areas. There
is also a patented process used by Final Coat's corrosion module
that uses radio frequencies. There are several options for a
consumer to consider.
Many dealerships offer this environmentally friendly technology as
an alternative that offers consumers a clean way of protecting
their vehicles from corrosion. Most modules are also transferable
to another vehicle. Where’s the proof? This technology has been
used for years on ships that float in salt water, bridges,
pipelines and underground tanks. This technology has been adapted
to the automobile sector and offers a ‘green’ alternative to
protect the entire vehicle from the road to roof.
Most manufacturers and independent operators will only provide a
limited warranty restricted by time and kilometers. Many
independent operators in fact have limits to the dollar amounts
that will be paid out and offer a limit of only one claim. Be sure
to read the warranty that an independent rust protection company
offers you and the details of their process before you invest in
having your vehicle treated by them. Also consider if they are
likely to be in business years down the road should you require a
If you live in a warm and arid part of the country, the process of
oxidation is obviously minimized however, if you live in a part of
the country that experiences the full wrath of winter and where
salt or other chlorides are used on roadways, protecting your
vehicle against rust is most definitely a justifiable
If you were going to lease a vehicle and had no intentions of
buying out the vehicle at the end of the lease, it would make sense
why you might not invest in a complete rust protection package.
Many customers who do lease their vehicles have their vehicles
undercoated solely for the purpose of driving a quieter vehicle.
Many consumers though, change their minds when their lease is up
and purchase the vehicle for themselves or as a gift to a family
member. Some dealerships recognize the value of rust protection and
offer a trade-in bonus if you trade-in your vehicle to them in the
It’s up to you. If you have confidence in the manufacturers’
warranty, give it a miss. If you want to insure your investment,
have your vehicle protected with an anti-rust treatment.
