Paint leveling determines whether a coating flows into a smooth, uniform film after atomization. Poor leveling can create orange peel, rough texture, edge mapping, or uneven gloss. This article provides a practical testing method using controlled spray gun settings, standard test panels, measured application technique, and inspection criteria suitable for automotive refinishing professionals.

Fragile workpieces such as thin plastic trim, small brackets, lightweight panels, and delicate repair areas require controlled atomization and softer airflow. Excessive air can push fine paint particles away from the target, causing dry spray, low transfer efficiency, and weak edge coverage. This guide explains practical steps for reducing airflow impact while maintaining finish quality.

Leakage at the cup-to-gun connection is a common but serious spray gun problem. Even small seepage can drip into fresh paint, disturb operator grip, or introduce air into the material feed. This guide gives automotive spray professionals a practical method to inspect, clean, reseal, and verify the joint before returning the gun to production work.
