The Item in My Kit
I bought NEIKO Gravity-Feed Spray Gun as part of my camper van equipment.
My coating purchases include a gravity-feed spray gun. During the van's exterior work, the sprayed bedliner result varied with the coating: Rust-Oleum pooled in places while my notes favored RAPTOR's more consistent finish.
Looking Beyond the Spray Gun at the Whole Coating Job
- I bought a gravity-feed gun for my coating equipment.
- I masked the van, sanded the exposed bodywork and cleaned it before spraying white-tinted bedliner.
- I compared the finished coating results in my diary: Rust-Oleum pooled in areas, while I preferred the more consistent RAPTOR result.


Camper Van Project Applications
A spray-gun comparison should include the nozzle, cup, connection and air requirement rather than the price alone. Those details define what else the painting setup needs. Steven returned this gun without using it, so its possible role in panel painting remains separate from an owner performance review.

Manufacturer Specifications And Instructions
| Specification | Manufacturer Detail |
|---|---|
| Model | 31216A |
| Feed | HVLP gravity feed |
| Nozzle | 2.0 mm |
| Cup | 600 cc aluminum cup with lid |
| Adjustment | Three adjustable valve knobs |
| Published Average Air Consumption | 4.5 CFM |
NEIKO lists a gravity-feed cup, a 2.0 mm nozzle and separate adjustment knobs for this model. For a camper-van painting project, cup capacity affects refill frequency and air consumption helps compare a spray gun with the compressor supplying it. I returned this gun without using it, so these are manufacturer details rather than results from my build.
My Purchase and Use Status
I returned this NEIKO spray gun without trying it. My preference after the painting work I did is to spend more on a sprayer such as the Graco, which worked well for me.
My Takeaway from This Job
The coating results in my diary guide my next finishing job. For choosing the equipment, cup position and the way the coating container connects are the concrete differences shown below.
