This was the Tetrajet version of Acidstorm I did based on the Cybertron Starscream Supreme figure, 50% scratch-built. The first thing I did was replace the original led for the eyes with a red one and a smaller battery. I then went with a black Krylon fusion base paint then misted over it with a flourescent green acrylic spraypaint. It stayed dark enough for normal lighting, but heavy enough to glow pretty bright under blacklight. After everything was painted and drybrushed, I lightly misted the robot mode with a glow-in-the-dark acrylic spraypaint that still allowed him to glow a little even without the blacklight. I'm now taking commissions on these guys.
