Lay-flat atomization
~3.5 mils per coat — smooth, consistent, no touchups.
Three guns in one
1.5, 1.8, and 2.0 tips included — epoxy to high-build covered.
Disposable cup ready
Works with 3M PPS, Sata, Mirka, DeKups, and more.
Lay-flat application
Shiny primer. Every coat.
FullFlow Atomization System
Most primer guns need post-spray block sanding to fix texture. The SHADOW's high-viscosity air cap geometry breaks up thick primers differently — forcing material through a wider fan at the pressure that matters, not the pressure that's convenient.
One verified buyer running PPG Hi Fill at 2 Bar, 4:1 mix described it as "shiny primer" — an effect he'd never seen from previous guns. Less block sanding. Faster to topcoat.
~3.5 mils per coat
12–15" fan pattern
6–9" from panel
Engineered for the booth
Everything a primer gun should be.
Three tip sizes in the box at one price — epoxy sealers through the thickest high-build primers, no extras required.
1.5 · 1.8 · 2.0
mm
All three tip sizes ship in every box — no extras to buy.
The fan pattern holds wide.
A 12–15 inch fan at 6–9 inches from the panel means fewer passes and less opportunity for a seam to show. The SHADOW's air cap is tuned for full-panel coverage.

Your disposable system already works.
The M16 × 1.5 cup connection is compatible with the most common disposable cup systems on the market. 3M PPS 1.0 and 2.0, Sata, Mirka, DeKups, Norton, SEM — adapters are available for all of them. No proprietary lock-in.

Built to spray all day.
The grip geometry keeps the gun balanced in hand at full cup weight. Trigger pull, fluid control, and fan adjustment are all positioned for a natural spray motion. Spray fatigue adds up across a long job — the SHADOW's ergonomic design is built for actual booth use, not a product photo.
→ Durable ergonomic design · verified in booth environments
Single-stage made simple.
Single-stage paints tend to be more viscosity-variable than primers. The three included setups give you a starting point for any single-stage mix — dial in the right tip, set your pressure, and shoot. The SHADOW handles basecoat-compatible single-stages without needing an additional gun.
→ Three setups cover the range — 1.5 through 2.0
Parts are available when you need them.
Additional needle/nozzle/air cap sizes and a full repair kit are available separately. If a tip wears or a rebuild is needed, you're not replacing the whole gun. Luma III supports the SHADOW long-term — U.S.-based, with parts in stock.

"I have never seen a primer gun lay down hi-fill primer like this gun — hands down the best primer gun I have ever used. The way this gun breaks up and atomises the primer is next level. By the way, I have never seen shiny primer before."

"It lays primer down smooth and consistent, even with the thicker builds. Having multiple tip sizes included makes it super versatile — whether I'm spraying epoxy, urethane, or even a single stage, it handles it with ease."

"I've used all of them on the market. This one is a beast right out of the box. 1.5, 1.8, 2.0 tips in the kit — and I picked up a 1.3 as well. Four guns in one. That's a no-brainer."

AIR-NET 3-Stage Air Filter

Restricting airflow at the fitting defeats the SHADOW's air cap. High-flow fittings deliver full CFM to the gun.
