1. A method for improving coating uniformity across first and second cylindrical parts comprising:

  • providing a first cylindrical part having a first inner surface coating along its length that is axially applied at a first axial speed setting using a spraying device;

    measuring a first and second diameter of the first inner surface coating at a first and second position, respectively, along the length of the first cylindrical part;

    comparing the first and second measured diameters with a standard inner surface coating diameter to obtain adjustment instructions; and

    determining a second axial speed setting for applying a second inner surface coating to a second cylindrical part based on the adjustment instructions to improve coating uniformity across the first and second cylindrical parts.
