You often hear the phrase mixing computerized paint. It is the concept of starting to use it in construction paint. When building a house, you go to the store, choose a color gamut among the 1000 available colors. The shop owner will mix the original colors with the formula to create the color you want.

Tinting car repair paint is not so simple. For each vehicle, we have about 50 common color codes. Each color code also has a formula provided by the paint manufacturer.

However, automotive paint tinting cannot use the exact formula from the supplier for each color code. Technicians must refine according to the car to have the most accurate color when repairing. Some causes of cars with millions of colors:

  • Paint techniques at the factory are not homogeneous.
  • Impact of weather after using process.
  • Vehicles after repairs at different garages.
  • The vehicle uses a metallic color, with the color running between angles, straight, inclined and half inclined.

  • Ability to perceive colors extremely well.
  • Know the color mixing process to ensure that when spraying onto the car, it is not deviated.

Sanding machine
The sanding process accounts for about 40% of the car repair time. At the same time, automotive paint has turned to dry sanding technology. Sanding machine is a very necessary equipment. Some advantages of sanding machine over hand grinding.

Dust is a huge problem in the process of painting cars. If you paint on the outside, make sure the surface of the vehicle after painting is dusty. In addition, the paint room has an air circulation feature that helps prevent paint dust from flying in the air and sticks to the vehicle.
The paint room has a large investment cost. We rarely see them in small garages.

Truss phase paint

When mixing, the technique will mix many original colors to create the car color. Therefore, having paint truss at the factory will make the adjustment much more convenient.
Currently, on the market there are many different brands of paint trusses. But Nippon's paint truss is probably the right choice. Nippon supplies 90% of car manufacturing plants in Vietnam. Nippon is the No. 1 paint brand in Asia, the product is very suitable for our weather.
