SHORT duration Glow In The Dark paint?

[billw]

Does anyone know of a GITD paint that has a SHORT glow duration? Something like 30 seconds to a minute? This would be for "interactive" GITD writing/drawing/etc where you'd want several-minutes-old things to be essentially invisible...

Does it have to be green? Glow Inc has red and orange glow paint that glows much shorter.

I have some old style (zinc sulfide ?) green glow powder that actually fluoresces brighter under UV but fades much quicker than the new stuff.

Glow inc has its zinc-based line of products:

Blood Red GID-paint:

Orange GID-paint:

Both of these will according to Glowinc's tests loose 90% of its brightness in 30sec, after 4 minutes into the test it had lost 99% of its brightness and then faded away under an hour or so, but it was really dim during that time...

the red glows really bright and dims almost immediately. The bad thing is that it smells like rotten eggs.

Even with green glow you will find that it has faded significantly in a short time.
