Seymour AutoFlow™ Professional Aerosol Spray System

Sometimes innovation doesn’t come from adding more — it comes from making what already works even smarter. That’s exactly what we set out to do with AutoFlow™, the world’s first inverted aerosol spray gun.

If you’ve ever spent more time cleaning your spray gun than spraying, this one’s for you.

The HVLP Gun… Without the Gun

For decades, Seymour has been the name behind professional-grade coatings that just work — trusted in shops, plants, and garages across America. But even the best paint can only go as far as the tool that applies it. So, we reimagined what a spray gun could be.

The AutoFlow™ Spray Gun gives you the control and feel of a professional HVLP gun, powered by nothing more than a standard aerosol can. No compressor. No hoses. No solvent cleanup. Just slide in one of our premium coatings — like E-Coat, 3-in-1 Primer, or Stainless-Blast — pull the two-finger trigger, and spray with a smooth, even fan pattern that covers more surface in less time.

It’s clean. It’s fast. It’s built for techs who have better things to do than wash out a gun at the end of the day.

Spray Smarter, Work Faster

AutoFlow™ isn’t a gimmick — it’s a real shop tool, built from the ground up to solve real problems. The ergonomic trigger eliminates finger fatigue, while the proprietary 45° elbow nozzle gives you natural spray angles and better control. Every detail was designed for comfort, consistency, and speed.

And because it’s a fully mechanical, battery-free design, there’s nothing to charge, maintain, or recalibrate. Pop in a can, pull the trigger, and you’re in business.

AutoFlow™ also plays nice with shop rules. For small jobs and spot repairs, you can stay under the 3 oz spray rule — meaning fewer booth bottlenecks and more cars out the door.

Perfect for Pros. Loved by DIYers.

If you run a collision repair bay, AutoFlow™ is the time-saver you didn’t know you needed. If you’re a weekend restorer, it’s the easiest way to get professional results in your garage without investing in an entire spray setup.

Because great results shouldn’t require a compressor, an air line, and half your Saturday spent cleaning equipment.

A Seymour Original

From the company that invented aerosol spray paint in 1949, AutoFlow™ continues our mission to make professional coatings more accessible, more efficient, and more practical. It’s innovation rooted in 75 years of experience — and made right here in the USA.

We didn’t just reinvent the can. We reinvented how you use it.
