Review on TCP Global Air Undercoating Spray Gun - High-performance Application Sprayer for Sprayable Truck Bed Liner Coating, Rubberized Undercoat, Rust Proofing, Chip Guard Paint - Pneumatic Automotive Air Sprayer by Harald Patterson

I bought these with a set of U-Pol Raptor liners but unfortunately these bottles do not thread onto this gun. I'm not sure what it does because it doesn't say anything about what it will work with. It sprayed the liner perfectly, but I had to use two hands to keep the bottle under the gun the entire time. It also does not include a fitting to attach to the compressor hose. Must buy these separately.
