The Ford no. 4 viscosity cup is used for measuring the viscosity of paints and finishes to ensure a flawless finish. To ensure the best quality finish on your project it is important that you use a material with the correct viscosity for your unit. If the material is too thick or too thin for your unit the finish could be compromised.
