This is a video of Fonzie from DipYourCar painting a car with a thermochromatic car pigment that turns from black to clear to reveal the color below when it gets hot (previously: painting a glow-in-the-dark car). Pretty cool, especially watching the color change in slow motion. I’m tempted to get this done to my car but I’m not sure if the pigment will adhere to rust and stickers. “Is that thing even street legal?” Nope, which is exactly why– “You only drive it through yards and on the sidewalk.” *smiling proudly* I have nothing more to teach you.
Keep going for the video, but skip to 5:15 if you just want to see the color changing.
