1. Pretreatment and Electrodeposition
In the pretreatment process, the entire body is degreased, cleaned, and coated with zinc phosphate by dipping after being. After the body has been cleaned with pure water, it is placed in an electrolytic bath of soluble primer (Cationic Electrodeposition). This produces a thorough corrosion inhibiting coating on the inner surfaces and corners of the body, pillars, sills or panel joints. Chipping primer is then applied to the most susceptible area.

2. Intermediate coat 1
The intermediate coat 1 is applied to the prepared surface in for further protection against damages.

3. Intermediate coat 2
The intermediate coat is matched to the color of the top coat.
