I wonder if there is some agent to add cheap plastic paint to make it
Fluorescent, -- Some Fluorescent paint is invisible if it is not
exposed to UV light and can be used ontop other paint like a varnish ,
could that be waterglass ?
Thank's |

Thank you.
I am a bit stuck with a trivial problem , a bit silli in fact.
As to use this paint I was building some projector for the UV light so
it can be directed over a distance, and everything went well, -- then
it happen that plain window glass seem to be a serious barrier towerds
the UV light , -- with this project that changed everything, so I has
to change the project before it can continue. Anyway thank you. |

As I recall, there are credit-card size cards which
glow when struck by infrared light used by installers
of IR motion detectors to find the IR beam. Maybe
you could find a way to use that technology. |
