CUPro paint from LessEMF in Albany New York is water based, therefore it is not a flammable substance and should be allowed as cargo on planes.
When I travel I print out TSA’s website for prohibited items indicating that there is no limit to the size of the container. I also print the CUPro paint data sheet again indicating this is a water based paint.
Everything is packed in plastic zip lock bags just incase the paint leaks.
TSA inevitably opens and inspects the shipping box and then they seal it back up with love.
