The gauge may now be read to determine the wet film thickness. The ends of the teeth or notches are visually examined, some will be coated or ''wet'' and some will not be coated or ''wet''. The wet film thickness (WFT) of the coating lies between the values of the smallest uncoated (dry) tooth or notch and the largest coated (wet) tooth or notch.
