So I called Day-Glo this afternoon and found I could order the same pigment, Blaze Orange AX-15. Minimum order is 5 pounds. I would have to pay for it this time. -rats! It seems it is the same pigment used in traffic cones. Luckily hsifyppah is a 1000 miles away, so I think I am safe from Midnight Banjo Playing Ninja Orange Thieves.
The order should arrive in a couple of weeks.
