I was inspired to try airbrushing after reading this article by nippper!

I wondered, "How can I achieve this glowing effect on a Zaku?" and gave it a try. The detailed process is in my production notes.

Since it's EcoPla, the base coat is already black, which is a great advantage.
I found airbrushing difficult until I got used to it, but I'm quite satisfied with the result for my first attempt. 😌

First time using an airbrush! Easy glow effect with eco-plastic. | 96pug's Gunpla works
