Saving you time and money.
That seals it.

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.

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.

The ideal nozzle depends on the kind of paint you’re spraying.

• For basecoats, 1.2mm to 1.3mm nozzles are typically recommended. They provide fine atomization for smooth, even coverage.
• For clear coats, 1.3mm to 1.4mm nozzles work best, allowing for a high-quality finish with proper flow-out.
• For primers, use larger nozzles, like 1.7mm to 2.0mm, to handle thicker materials and build up the surface evenly.

Devilbiss offers multiple tip sizes for most guns, so you can match the setup to your material and job requirements. For more detailed information, check out these resources on our automotive finishing hub.

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.

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

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

The current bumper pad is aggressive enough to adequately abrade most primed bumpers. However, it is not rigid enough to level the primer layer (remove the uneven spots) on the bumper.

One can use the current bumper pad to clean and degrease a primed bumper. But it will not level the primed surface sufficiently and a sanding process will still be required.
