Chemical/Gas detection paint

[Phil Waterman]

Always thought that it would be interesting to use temperature sensitive paint in the correct color range for a display substitute for Gas Detector Paint. After all real Gas Detector paint is going to do one of two things: Not change color or if you are in an urban pollution area tell you not to breath the air.

But if you used a temperature sensitive or light sensitive paint for the warning patch of paint would be changing all the time, making for a much lively vehicle display particularly if you are diving for your gas mask every time it changes color.
