Can they be spray-applied?
Just add enough GOLDEN Airbrush Transparent Extender to them to reduce to the proper viscosity. We suggest to start with equal amounts of color to Extender and mix until smooth, then continue with more Extender until you reach the proper viscosity. This lessens the chance of lumps of color which can clog the spray equipment. Refer to the Information Sheets "Beginning Airbrush Tips I & II" for more tips. We also have a new line of Fluid Interference as well.
