I made a Gonk droid, one of many I will be making. Being that it's made of hard plastic, I was able to spray paint it. Painting Gonks in the past i used acrylic, and it just scratched off. Spray paint is more durable. Then I added model kit parts. Then gave it a series of washes, and dry brushings.
HO-9 Was a modified Gonk droid owned by the Mining Guild. He was modified for high output. He sported a pair of heavy duty outlets, a water cooled generator, and a high flow oiling system.
