ya that black light stuff just never looked that good to me..... i shoulda tried the black light without that uv paint stuff.....

 

Yea I was currious on that too so here's a side by side pic of the needles with out and one with the uv reactive paint next to my 22" long house uv light:

**cell phone camera pic, thus the blurr**
To get the full effect you need to add a few layers to the needles and it doesn't seem to effect needle action in any way.
