Feikenee Undercoating Spray Gun Kit — 25oz (750ml) Suction Cup, Stainless-Steel Body, Ergonomic Trigger

The Feikenee Undercoating Spray Gun Kit is a stainless-steel, suction-feed spray gun with a 750ml (25oz) cup built for automotive undercoating, bed liners, and general-purpose coatings.

This compact spray gun kit brings a durable metal body, a large-capacity aluminum fluid cup, and an ergonomic trigger together to make undercoating and protective spraying faster and cleaner. It’s designed to accept common 1/4" NPS air hookups and withstands higher pressures, while still performing best in a moderate pressure range for smooth, even coatings.

How does this spray gun handle larger jobs?

The included 750ml (approx. 25oz) aluminum suction cup reduces refills for larger panels or full-vehicle undercoating projects. Its wide opening speeds up topping off and cleaning, so you spend less time stopped and more time spraying.

• Large 750ml aluminum fluid cup for longer runs between refills
• Wide cup opening for easy filling and quicker cleaning
• Durable stainless-steel gun body for jobsite resilience

What spray pressures and coatings work best with this tool?

The gun is rated to a maximum 15 bar (220 psi) but delivers optimal atomization and control in the 3–4 bar (around 50 psi) range. It’s suited for typical automotive protective materials such as rubber primers, bedliner-style coatings, and standard undercoating formulas.

• Maximum safe pressure: 15 bar (220 psi)
• Recommended operating pressure: 3–4 bar (approx. 50 psi) for even finish
• Compatible with common automotive coatings and primers

Is the gun comfortable and simple to use for extended tasks?

Ergonomics were considered in the handle and trigger design to reduce hand fatigue during long sessions. The lightweight construction combined with an easy-grip trigger lets you maintain steady control for consistent coverage on awkward vehicle underbodies and wheel wells.

• Comfort-focused trigger and grip for reduced fatigue
• Lightweight construction for easier maneuvering in tight spaces
• Suction-feed design keeps fluid flow steady on varied surfaces

What comes in the kit and how does it connect to my compressor?

The kit ships with the stainless-steel spray gun, a 750ml aluminum suction feed cup, and a standard air coupler for quick connection. The 1/4" NPS air inlet fits common shop lines and makes hooking up fast so you can get to work with minimal setup.

• Included parts: spray gun, 750ml suction cup, air coupler
• 1/4" NPS air inlet for broad compressor compatibility
• Designed for fast hookup and simple, reliable operation

Who is this for? The Feikenee Undercoating Spray Gun Kit is aimed at automotive DIYers, detail shops, and small-scale pros who need a rugged, easy-to-clean suction-feed spray solution for undercoating, bed-liner style coatings, and protective primers. If you value a metal-bodied tool with a large fluid cup, ergonomic handling, and standard compressor compatibility, this kit provides a straightforward, capable option for routine protective spraying tasks.
