Finally decided to try some paint on my Soundwave. I think the color of the grey plastic is very different from what I saw in the movie. Or maybe he is a reflective color and is just reflecting the darkness of space. Anyways, here's the first part I did, one of his panels. This is the first coat, will touch up on it later when it has dried.
This project will take quite a long time since he has many pieces. This part here took me around 1 hour. The black wash was done a bit too heavily, but I'll see how the second one comes out. Worst case is I will have to remove the paint of this one and do it over again.
