The Item in My Kit
I bought TCP Global Undercoating Spray Gun as part of my camper van equipment.
I bought an undercoating spray gun among the van's coating tools. My diary identifies Fluid Film Black on the undercarriage and records a separate sprayed-bedliner job on the exterior body.
Keeping the Underbody and Exterior Coating Jobs Separate
- I bought the suction-feed undercoating gun among my coating tools.
- My diary records Fluid Film Black on the undercarriage.
- The exterior body received a separate white-bedliner treatment with its own masking and finish work.
Camper Van Project Applications
Bedliner texture depends on the coating and the application equipment together. A gun used for a textured coating is a different choice from a fine-finish paint setup. Steven's experience with heavy, uneven material delivery makes control of the texture a central comparison point here.

TCP Global lists this gun as the UG8405, with a suction-feed cup and an air regulator with gauge. The cup holds the coating below the gun, while the compressor supplies air through the inlet. The listed air consumption is separate from pressure: both matter when matching a compressor to a spraying job. This format is intended for automotive undercoating, chip guard and sprayable bedliner. My review below records the uneven, chunky application I experienced with the Rust-Oleum bedliner and why I preferred the gun supplied with the RAPTOR kit.
My Experience with This Tool
I tried this gun with Rust-Oleum bedliner and did not like the combination. I had less control over the spray, and it deposited heavy chunks of bedliner on the van instead of the even appearance I wanted.
I preferred the gun supplied with my RAPTOR kit. It sprayed more evenly in my use, and changing the compressor pressure let me adjust the spray. If I did my van's bedliner again, I would try a finer application rather than repeat the heavy, chunky texture I have now.
My Takeaway from This Job
The underbody treatment and the exterior finish were separate jobs in my build. Here I compare the equipment by container arrangement: a lower cup, an upper cup, or a gun connected to a protective-coating container.
