After assembling the sheet metals and aluminum parts to form the car body, comes the painting process. In the painting process itself, involves many other processes to ensure the body of the car is painted perfectly to avoid corrosion.

First, the body of the car will be washed by using heated degreaser fluid to ensure the body is free of oil. Commonly, the degreaser fluid is heated with a steam supply, but by using hot water generated by heat recovery in heat pumps, this can be avoided.

Then, the car body is coated with phosphate acid solution to protect from rust, ensure metal cleanliness, and better adhesion of paint on the car body. After coating, the car body is painted using an electrodeposition painting system which uses a plate heat exchanger to control the temperature of paint to ensure optimum results of paint.

Lastly, the painted car body is rinsed with water for an even and neat final paint result.
