It is important to adjust the spray pattern properly.
*The proper spray gun pattern is elliptical in shape (8-10 inches in length) with an even amount of material across the entire surface.
[some airbrushes will use a circle pattern]

* If the paint is heavy on the top or bottom could mean a restriction in the fluid flow, usually at the fluid needle and/or air cap. Clean both and retest
* A crescent shaped pattern could mean a restriction at the fluid needle and/or air cap on one side. clean and retest
*Heavy in the middle could mean too little air flow.
*Divided in the middle could mean too much air flow.
With the air cap turned 90 degree's (so material is running horizontal) and a heavy amount of material sprayed, the test pattern should be 8-10 inches long elliptical in shape. There should be "runs" a consistent length along the whole pattern.
