What types of paints can be airbrushed?
Any paint (or liquid) can be sprayed providing it can be thinned to the required consistency (viscosity) that allows the paint to flow through the airbrush. This includes acrylics, watercolours, oils, enamels, automotive finishes, alkyds. For paints that include aggressive solvents (i.e. cellulose) you will need an airbrush that contains no rubber seals or valve seats. Rubber is normally replaced by PTFE for such applications.
