Primer application on bare or repaired metal depends on consistent gun travel speed, overlap and film build. This article gives automotive refinishers practical standards for controlling LVLP gun movement during metal priming, including distance, overlap ratio, pass timing, edge strategy, wet-film verification and adjustments for panel geometry so technicians can build an even primer layer without dry spray, excessive texture or runs.

When an LVLP gun is paired with a small or low-pressure compressor, the pressure shown at the wall regulator can be very different from the pressure actually reaching the gun while spraying. This article provides a practical body-shop method for measuring dynamic pressure loss, checking hose and fitting restrictions, evaluating compressor recovery, and tuning the gun without masking supply problems.

Paint buildup around the air-cap horns and center holes can quickly distort an LVLP fan pattern, increase edge loading and produce uneven atomization. This article explains how professional refinishers can identify cap-related pattern faults, isolate them from fluid-tip or pressure problems, clean the cap safely without damaging precision holes, and restore a balanced fan before production spraying.
