Thread: UV reactive writing on gravestones

Tweet

Has anyone used UV dye on top of gravestones?
I was thinking of painting "boo" or something over the top of some gravestones that I have. Using transparent UV dye. Then use a flood to light up the gravestone as usual, but then have it fade out and fade in the UV light to make the "Boo" show up out of nowhere....
What do you think? I think it would look creepy and at just a little more detail to a standard part of the haunt....

Sounds like a great idea. I have some of the reactive dye on order now, but it's water solubil so I doubt it would last out in the weather. I suppose you can add it to any water based latex clear coat which should work. I'm none too sure about the dye's staying power exposed to sunlight or simple aging though.
