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

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.

Worked great for Fluid Filming my 97 Jeep XJ that came to MI from AZ. For the price, can't beat this gun it's flippin' awesome!!! Has everything you need w/ the nozzles ect. Cup closes securely, did not open when I didn't want it to & I had it in all orientations while applying the Fluid Film. I did set the can of fluid film (and the bottom of the feed cup) in hot water before spraying as it was about 45f outside when applying.

Unit construction is better than expected for this price point. It will not blow your socks off but it's not paper thin. The regulator on my unit does nothing other than turn the air on or off. I have an external regulator off the tank, was not a deal breaker for me. Every connection on the gun needs to be removed and taped to prevent leaks. The adapters work for their intended purpose, the main sprayer functions very well. My intended use with this gun was to create my own adapter with a thin 90 degree wand for low pressure spray into door skins, rockers, frame, etc. The way this unit is designed will not allow that to work, because it needs a very specific amount of pressure inside the line. It just starts pressurizing the relief hole in the product reservoir with the small amount of restriction created by the different tip. I will not hold that against the product, they do not advertise any such capability. However, learn from my experience that the spray accessories for this gun cannot be modified in any way. Small issues, overall it does what it claims to do for a reasonable price. If you added a 90 degree wand accessory that allows you to do a complete professional job you could charge $100 for this unit and it would still be a deal. The included accessories are limiting, as they will not fit into any body skins. However, if all you need to do is flat surfaces like on a sedan floor, or simple equipment, this could be your perfect sprayer.

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.

I have used this on about 6 cars and trucks so far. I also used it at work a few times. 90 psi smooth spray. get the rotating or sniveling 3/8 air nozzle. Helps when setting gun on floor. No pressure on air line. Works as should. Just don't be the bull when tightening the lever on top. I've gone thru 10 gallons at home and who knows at the shop.

I used this spray gun with Raptor Liner for my Jeep TJ hardtop, and it worked perfectly. The spray was nice and even, with no clogging or spitting. Cleanup was simple, and it felt sturdy in the hand. It made the job a lot easier and gave me a professional-looking finish. If you’re planning on using Raptor Liner or any rust-proofing projects, this gun is definitely worth it.

This worked perfectly No leaking. The whole undercoating is a messy adventure but this sprayer made it dealable

Did the job, for the money it's a good deal, shipping was quick, I overtightened the cup and bent the posts on the cup but didn't break them, it's because the cup thickness is weak, And don't use a bag in the cup, the suction will block the pickup tube, once i figured that out it sprayed fluid film good. Goodnuff

Wow, finally a gun that sprays heavy material. Tired of returning garbage. Thank you manufacturer for stating the truth.. From a 40 year auto body tech. I will order another so I can have one for my undercoating and one for rocker guard.

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.

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

Works well for me
