Method of determining coating uniformity of a coated surface

A method for applying a coating comprising:

• obtaining a subject cylindrical part including an inner subject coated surface applied using a spraying device at a first operating condition, the inner subject coated surface including a longitudinal axis and a cross-section, the cross-section intersecting the longitudinal axis at a center point and including end points located on an outer perimeter;
• measuring the inner subject coated surface to obtain subject coating data including distance values, the distance values each being a distance between the center point and one of the end points and obtained by measuring coordinate x, coordinate y and coordinate z values of each of the end points of the cross-section;
• comparing the subject coating data to standard coating data to obtain comparison data, the standard coating data being obtained from a standard inner coated surface;
• and
• adjusting the spraying device based on the comparison data to have a second operating condition different from the first operating condition.

• reducing peak height of one or more coating spikes on the subject coated surface by contacting the one or more coating peaks of the subject coated surface with an abrasive;
• measuring the inner subject coated surface to obtain subject coating data including distance values, the distance values each being a distance between the center point and one of the end points and obtained by measuring coordinate x, coordinate y and coordinate z values of each of the end points of the cross-section;
