Invisible UV Spray Paint

I used this to add some flash to the backplate of my video card inside a new PC build. Worked great; glows a very intense red under my UV cathode tubes (and this was done over flat black). Gets brighter the closer it is to the light source. I was very impressed and might do more with different colors. Wish it wasn't so expensive.

Make sure you are using a REAL UV blacklight! LED lights that claim to be UV don't always work and purple fluorescent lights are NOT blacklights! A true blacklight will put out ZERO actual "light" and ONLY react to UV-sensative material, like this paint.
