InoKraft Undercoating Spray Gun Kit with Suction Feed Cup, 360° Flexible Wand & Straight Hose, for Truck Bed Liner, Underseal, Rubberized Undercoating & Rust Proofing

This thing really gets the job done! I've been using it for a while now, and it's been super reliable. It sprays that protective coating without any fuss whatsoever. Honestly, I wouldn't hesitate to suggest it to anyone looking for a solid option. It's definitely a worthwhile purchase.

Works great! The attachments make it easy to coat hallow spaces such as rockers. I spray painted underboard rust coating using a small pancake compressor and did my entire Ford Excursion in less than an hour. I was surpised how little of a mess it made. I used rustoelum underbody paint. Very good product!

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.

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.

Should ha e bought this a long time ago works great

Works great for fluid film.

I finally got tired of hand painting my truck frames. Bought this cheap entry level sprayer. It came with a good amount of accessories. Sprayed the undercoating without any issues. I def wouldn’t use it for anything other than bed liner or frame painting. I would purchase again.

Perfect for home mechanics. Works very well with fluid film under coating. Love the pressure adjustment gauge on the sprayer.

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.

I read all the reviews before I bought this and I must say I didn’t have one issue of any of the other reviews everything works perfect no leaks the gauge works as it should it sprays as good as the $200 guns I’d recommend this gun 100% ,,the only thing I have to do is make a 5’ wand to spray inside my cargo trailer frame other than that it’s perfect

The latching style cup is easy to fill. It seemed to have no trouble siphoning PB surface shield and atomizing through the extension. I am happy with it’s performance given the price point.

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
