InoKraft Undercoating Spray Gun with Suction Feed Cup, 360° & Straight Spray Hoses, for Truck Bed Liner Coating, Rubberized Undercoat, Rust Proofing

This is hands down the best rustproofing gun I've used. It replaced the the common Arslan/Napa type which only last a year if you're lucky and will probably give trouble before that. This gun was used to spray a wax/oil hybrid coating at below 10*C and atomized beautifully, it really throws it on. If there are any shortcomings to speak of I guess the hoses could be a little longer and maybe the cup could hold a little more, but these are minor issues if even issues at all. Personally I'll not be going back to the other types any time soon. Auto Tech recommended!!!

The spray gun itself seems to be working well so far; it has already sprayed done for the all panels. Clean the gun details after the job every time was very important. However, some accessories are no longer functioning properly. The Paint storage tank size is too small as a toy, so I have to add the paint frequency and waste the work time. Air hose connector is EU type and cannot connect to the air hose normally, the type should be choose the Nitto to matched the hose connector in AU. Air pressure adjustment knob has no function. It screw opens directly to the air pump's set pressure; there are no adjustment functions whatsoever. So the part Air pressure gauge and Air pressure adjustment knob were useless too.

This gun is a very good set for undercoating! Price and quality are very good. Works as it should! It works as well as the $150.00 gun I have and has a larger opening to fill it which makes it much more convenient. I’m not sure how long it will last but I can’t see any reason it won’t be around a long time as long as it’s maintained.

I used this gun with Fluid Film to undercoat my F350. It was recommended by others for price and ease of filling and worked very well. I had never used Fluid Film before and it is relatively heavy molasses like product. Some of the other spray guns have narrow neck opening to fill the material in the container and I can see this would be a challenge where this large mouth opening was very easy and appreciated. Along with that, the gun was simple to use and adjust the spray. I used the 360* tube for inside the frame and the normal tip for spraying other outside areas. I took advice to preheat the Fluid Film to help with spraying so I put a hair dryer next to the container for a few minutes and stirred with a stick to increase the viscosity and had no problems with the spraying at all. I would recommend this spray gun for ease of use and cost value.

Every bolt and screw needed to be snugged up, but worked better than expected. I sprayed WoolWax to undercoat my truck and inside the frame. The sprayer worked great at 70psi. Atomized the thick WoolWax very well giving even and predictable coverage. Flow was way to adjust and the 360 tip worked exceptionally well. Highly recommend
