Earlex Viscosity Cup (Ford #4)

This viscosity cup from Earlex is used to measure the viscosity of paints and finishes prior to spraying. Just submerge it in your coating, lift it out, and time how long it takes to drain. Add the appropriate thinner until you reach the correct drain time for your spray needle. This simple process is an invaluable step toward ensuring a flawless finish. Compatible with all Earlex spray station models.
