What does MAX mean in gundam model?

A painting technique, founded by MAX Watanabe, is called MAX.

Increase the color level through shading, and enhance the authenticity and three-dimensional sense of the parts. Compared with monochrome painting, MAX painting highlights the highlights in the center and enhances the shadows at the edges, making the surface look more natural and rich. This layer-by-layer painting gives rich expressive power to the works that monochrome painting can't achieve, and makes the works more vivid and real while enhancing the details. If you have used a spray gun, learned how to mix paint colors, and mastered the strength and air pressure of the spray gun, then MAX painting is not a difficult skill to master. Because it is layered spraying, it is also feasible to make some adjustments and finishing.
