I got some UV reactive clear spray paint to try on some skeletons.
You can buy it from The Butcher Shop in Western Australia.
Freight is not cheap ($25 to QLD) and the paint was about $20 a can.
One of these skeletons has had two coats of the UV paint.
The general illumination is a white LED light.
With the LED UV light on, you can see the left one glowing.
The white illumination is still on.
The white illumination has been turned right down.
The UV effect really pops.
