HISTORY OF COLLISION REPAIR
Time was, if you had an accident, the call went out to the insurance company - to the collision shop - or several shops get the lowest bid and in no time at all, the vehicle was repaired.
The facilities, training, and equipment were simple. Use a torch to cut, shape, and bend. Use something substantial as
an anchoring point - maybe a tree and then just pull.
Use plenty of solder or body putty to make it look good. With the frame and body vehicle, the job was easy; first
straighten the frame - then fix the mechanical components and the body work was cosmetic. This was all well and good
until the mid - '70s.
Then, the designers, engineers, and manufacturers had to find ways to make the vehicles energy efficient - and that
meant unibody cars. The unibody concept wasn't new - back in the '30s the Chrysler Air Flow had it - race cars have it and now the driving public worldwide has it.
The change came quickly. Manufacturers devoted time, money, and talent to delvelop the unibody car.
The public was ready to buy and did!
But then came the problem! The collision repair industry wasn't given the luxury of taking their time to train people in the
new technology - or take time to plan for new equipment.
The collision happened and the vehicle had to be fixed. Cars that were repairable were being totalled.
Cars that were repaired were not repaired correctly. Everybody was in a quandary - auto manufacturer - insurance
company - repair equipment people - body shops - and repair technicians.
The problem started in the early '70s and body shops are still catching up today. Yesterday's "ding" is today's "crash". It
takes trained technicians and sophisticated equipment to do the repair today.
That's why DaimlerChrysler is taking the time and effort to get the right information into the hands of the people that
handle the repair job.BackToIndex

Corrosion Protection
Factory Applied Corrosion Protection
During the manufacturing of the unibody car, the manufacturer applies "corrosion protection" using specialized
manufacturing processes. This system is not duplicated in the collision repair body shop. However, the body shop still
has a responsibility to apply corrosion protection to the unibody vehicle. So, the collision repair shop must use
alternative materials to do the corrosion protection job after the repair.
This corrosion protection is required regardless of the environment and weather conditions the vehicle will be operated
in. Corrosion protection is as important in the desert as it is at the seaside. Corrosion damage can literally destroy the
structural integrity of a unibody vehicle from within. Many corrosion protection systems are destroyed during collision
repair operations. Metal finishing, metal working and fatigue can cause the breakdown of many of the corrosion barriers
installed at the factory. The use of heat for stress relief and welding also destroys factory installed corrosion barriers.
These corrosion barriers and corrosion protection systems must be replaced after collision repair to ensure that the
structural integrity of the unibody will remain intact throughout its life. In the past, only vehicles with aftermarket or afterdelivery corrosion protection systems installed were serviced after collision repair to restore the corrosion protection
system.
An understanding of the types of corrosion which affect the unibody vehicles will assist in understanding why the factory
protection systems are important, how the factory protection systems consist of and how the systems' protection is
replaced after collision and electrolytic corrosion. Some of the more common types of corrosion are crevice corrosion,
pitting, galvanic corrosion, stress corrosion, cracking, fretting, and erosion corrosion. BackToIndex
Page 32
Corrosion Protection
Crevice corrosion
Crevice corrosion is a form of localized attack that occurs in areas on metal surfaces exposed to the elements.
Examples include spot weld lap joints, threaded or riveted connections, gasket fittings, porous welds, valve seats.
Pitting
Pitting is the corrosion of a metal surface at points or small areas which look like a small hole in the metal.
Galvanic corrosion
Galvanic corrosion is the type that occurs when dissimilar metals are in electrical contact while immersed in an
electrolyte.
BackToIndex
Page 33
Corrosion Protection
The penetration of corrosive solutions into these small areas, with widths that are typically a few thousandths of an inch,
can result in various types of failures: the metal surface may become rusty in appearance, operating components may
seize when protective coatings may have been removed from the metal surface. The coating of zinc on steel, known as
galvanized, is an example of sacrificial cathodic protection.
An example of galvanic corrosion on the automobile is a stainless steel trim molding on a painted mild steel. When the
paint becomes damaged, a galvanic corrosion cell is formed between the passive stainless steel (cathode) and the steel
(anode). The corrosion leads to what would look like a rust stain. Methods of reducing galvanic corrosion include the
use of compatible materials, minimizing of cathode-to-anode areas, the insulation of dissimilar metal contacts and the
use of thick, replaceable sections.
Stress corrosion, cracking, fretting, and erosion corrosion.
Corrosion cracking is the early cracking of metals produced by the combined action of tensile stress and a corrosive
atmosphere.
Corrosion fatigue is cracking due to the action of stresses and corrosion. Methods of reducing corrosion fatigue include
the reduction in stress and the use of coatings.
Fretting is the deterioration of a metal at contact surfaces due to the presence of a corrosive and relative motion
between the surfaces. The two metal surfaces initially are covered with an oxide film that becomes abraded during
vibration. The results are oxide particles that become corroded. During the collision repair process, the factory
protection materials become damaged from working the metals, or from the use of heat in the repair operations. If
these factory protection materials are not replaced with some similar protection material after repair, a corrosion hot
spot is formed. A corrosion hot spot is a small unprotected area surrounded by a protected area throughout the rest of
the vehicle. the hot spot effect causes rapid deterioration of the unprotected area. This deterioration takes place at a
much faster rate, sometimes 10-12 times faster than if the entire car were unprotected. The hot spot effect is created
because all the corrosive factors are channeled to the unprotected area much the same way all material flowing through
a funnel is concentrated in a small area. This hot spot effect means that corrosion failures to the unibody structure
could occur in a short period of time even in an atmosphere normally not subject to corrosion. The hot spot effect can
cause rapid deterioration of unibody structures from corrosion damage in a desert as well as seaside.

Corrosion Protection
The types of materials used in rustproofing application include oil based materials, wax base materials, primers and
color coats. The most important properties of rustproofing materials are adhesion, toughness, and the resistance to the
environment. The best coating in the world is not effective unless it is present in the right place at the right time.
Corrosion Protection Information
When making the collision repair, refer to the manufacturer's information on where corrosion protection and sealants are
applied. Be sure to follow the recommendations. The application process is usually included with the material
manufacturer's information so be sure to read and understand it before proceeding with the repair.
Collision Repair Corrosion Protection Materials
The materials must provide good electrolyte barriers. The material must also be able to penetrate tiny crevices and
prevent abrasive corrosion. The material must be compatible with paint systems as many areas of the car must be
treated before paint is applied.
Materials containing silicones will cause paint conditions such as fish eyes if they are applied before the repaired vehicle
is painted. So no silicone containing material is to be used. As many of the repair areas are more accessible before
final assembly and painting, the non-silicone type materials are a must for this type of application.
When protecting an enclosed area, fog type properties for the corrosion protection material are a plus. The fog
properties make the material much less susceptible to operator error or misapplication. With a fog type material, once
the material is introduced inside of an enclosure, the fog spreads rapidly and evenly into all areas including tiny
crevices. The fog type materials do not require direct spray application to be effective. Fog type materials are also very
effective in coating over any existing rusted or corrosion damaged areas and preventing further corrosion of these
areas. This is especially important on repairs of older vehicles.

Page 35
Corrosion Protection
Spray Accessibility to the Repair
Being able to achieve fog spray penetration into enclosed cavities as well as open areas requires application equipment,
which includes an assortment of wands of various lengths and design.
Some areas are more effectively treated by brush application of corrosion protection material before they are
assembled. A good example of this is an inner and outer engine compartment side rail area. Brush application to the
inside of these areas as individual pieces is easy before assembly and can be followed by a light fog application to the
weld areas and the crevices formed during assembly after the rails are assembled. Brush application keeps the foreign
material from getting between welded joints during assembly yet gives good coverage to general areas with easy
application. The material selected in addition to paint compatibility features and fog application features is also an
excellent brush application material. Repaired areas, boxed in or closed in are more easily treated during assembly
using fog and brush on techniques. Care must be taken to keep the corrosion materials away from the welding areas as
welding contamination might take place. Brush-on applications are used before welding and fog in applications are
used after welding assemblies together.

Corrosion Protection
Desired Characteristics of Corrosion Protection Material
1. Corrosion prevention material- The material must displace water to prevent corrosion. This can be tested by
spraying water on an open panel on the floor, then spraying the corrosion preventative material over the watered panel
and observing if the material displaces the water.
2. Creepage of material- To insure thorough and complete protection coverage, the material should have a "creep"
capability, approximately 1/4 inch per minute while drying. This assures protective penetration of pinch welds, cracks,
etc.
3. Safe material- Material should be non-combustible when dried and when wet unable to support a fire after ignition.
4. Clean-up- The material should be of a viscosity which inhibits runs or drips. Overspray on a vehicle's painted surface
should wipe off easily without solvent when wet, with solvent when dry. The material should also dry clean off clothing.
5. Guarantee/Warranty- The corrosion protection has to be done to maintain factory corrosion warranty.
Manufacturer's recommendations must be followed.
