I think the lens pieces look great. I used semi gloss black on the main panel and the eye piece and I like the look of that. And the lower grill is basically molded in gun metal so I didn't even paint that. The finished piece looks great on my wall and I think I'll even buy another one so I can have two in the house.
How did the HAL 9000 decal cover over the black? Is it opaque? I'm worried that I'll need to spray the area it goes silver or put down some white decal first.
