The word corrosion has been used to define the process in which a material is totally or partially destroyed when subjected to chemical, electrochemical or electrolytic attack on its surface or microstructure. Automotive painting has to comply with two basic requirements: anti corrosive protection and appearance. The anti corrosive protection of a steel sheet depends fundamentally on the surface preparation accomplished by phosphatisation, electrophoresis and primer while appearance depends on the finishing paints (enamel and varnish) which must also provide good protection against surface wear and intemperism. The good quality of electrophoresis paint is a function of various physical & chemicals control and adequate addition of deionized water and chemicals. Since painting is a complex task, defects may appear for various reasons. Elimination of the possibility of defects demands good knowledge about the equipment (bath, deionized water production, filtration, chemicals addition) and the procedures followed
