Neon pigments for Poly Resin

Anyone know of a source for neon colors for poly resin?  I have everything fiberglass HI sells and that FoamEZ has but I am looking for some more colors for a new project.

shapers.com.au has neon tints.  I just grabbed the pink and it is very very neon!!

in the shop I found some neon pigments (here in germany) they told me to make a white underground first to get them bright. 

Did you buy Fiberglass Hawaii powdered neon tints? 

Neon tints are really hard to find & to get them super bright takes practice.

Try mixing them with an opaque white to get a more vibrant color

Whant to build next board with epoxy and neon pigments. Can I use every kind of neon colour pigments or do I need special ones? What should I look for?
