Spraying with Paint
Preparing the Spray Material
Paints are usually sold in a spreadable, undiluted state. The paints
usually need to be diluted for use with the spray gun. You will find
guidelines for sprayable dilutions in the following Viscosity Table
(viscosity = consistency of the paint).
You can achieve the correct dilution by using the viscosity test cup.
