What type of spray gun is best for cars?

HVLP guns are ideal for basecoats and clearcoats because they reduce overspray and improve transfer efficiency—saving paint and money. Trans-Tech guns (like many DeVilbiss models) offer a bit more speed and atomization power while still meeting transfer efficiency requirements. For top-tier results, professional painters often choose high-performance guns like the DeVilbiss DV1 or GTi Pro Lite, which are engineered specifically for automotive base and clearcoat applications.

What’s the difference between HVLP and LVLP spray guns?

HVLP (High Volume Low Pressure) spray guns use a high volume of air at low pressure to atomize paint, reducing overspray and increasing transfer efficiency. They’re great for getting a smooth finish while minimizing material waste. LVLP (Low Volume Low Pressure) guns, on the other hand, use even less air, which makes them ideal for shops with smaller air compressors. LVLP guns also create less overspray and can offer better control on detailed work, though they may spray more slowly than HVLP guns.

What size nozzle is best for automotive paint?

The ideal nozzle depends on the kind of paint you’re spraying: For basecoats, 1.2mm to 1.3mm nozzles are typically recommended. For clear coats, 1.3mm to 1.4mm nozzles work best. For primers, use larger nozzles, like 1.7mm to 2.0mm, to handle thicker materials and build up the surface evenly.

What maintenance is required to keep my spray gun performing like new?

Regular cleaning after every use is critical. Use appropriate solvents and cleaning tools to flush out material residue. Periodically inspect and replace wear parts like needles, nozzles, and air caps to maintain optimal performance and spray quality.

Can I use disposable cup systems with DeVilbiss spray guns?

For the best results, we recommend using the DeVilbiss DPC (DeKups) disposable cup system, which is designed to reduce cleanup time and prevent contamination. DeKups work with all coating types, contain integrated mesh filters, and offer convenient ratio markings for accurate coating measurement.

What should you do if your spray gun is pulsating?

Torque your fluid tip to 15-20 foot lbs. and tighten the fluid needle packing.

How do you fix a spray gun that has a top or bottom heavy pattern?

You can rotate the air cap 180 degrees and if the heavy pattern changes, you may have a dirty or damaged air cap. If it doesn’t change, then you may have a dirty or damaged fluid tip.

Can the DeVilbiss Bumper Prep Pad be used on primed bumpers?

The current bumper pad is aggressive enough to adequately abrade most primed bumpers, but it won’t level the primer. It can clean and degrease a primed bumper but requires a separate sanding process for leveling.
