Hey I think I had that Hot Wheels growing up.
Guy Paints Car With The Brightest Available Glow In The Dark Pigments

This is a video of Fonzie of DipYourCar.com (which sells a kit if you want to do this to your car) painting a Mitsubishi Lancer Evolution (‘Evo’) with paint that has both KryptoBright and LIT glow-in-the-dark pigments added for MAX GLOW IN THE DARKAGE. The result is pretty impressive. Perhaps even more impressive though is the ability of anybody to just look at this car and know exactly what it sounds like speeding away from a green light.

Keep going for the video, but skip to 9:15 for the reveal and some cool flashlighting to really make it glow.
