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.
