JEC It is NOT paint but epoxy base tint. Can't speak for Edmonton, but there is a few shops here " Industrial Plastics" is 1that specialize in fiberglass material and products, they carry many colors of tint especially made for epoxies and glass resins.
If you have trouble finding any PM me as to color you want , I will be in Edmonton for the CHAS show and would be happy to give you some, as it tends to come in larger quantities than you or I will ever use in a lifetime.
