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.

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.

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.

Took a little fiddling with the pressure knob but works great now.

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!

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.

Worked great!

VERY HAPPY WITH THIS PURCHASE

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 is an excellent spray gun for Fluid Film. You don't need to heat up the fluid film it will spray directly from the gun. You just need to adjust the spray tip until the fluid film starts spraying. The provided air regulator is a little loose when attaching to the spray gun so make sure to use the provided teflon tape with 6-8 wraps and it will seal with no air leaks. This gun worked great and was able to undercoat my Ford Ranger in 20 min.

Received today, returned today. Product was defective. The piece that locks the cup to the gun was pressed in the wrong spot and it could not function and attach the cup to the gun.....ordered a second one and hopefully it is not defective....looks like a nice gun if it was properly put together. ***UPDATE***... Received my money back and ordered another gun....this one works great!!! Updated rating from 1 star to 4.

Very impressed. Started doing my truck with fluid film aerosol cans, but when I realized I was going to need more than anticipated and decided to do our car as well, I went ahead and ordered this with a bulk gallon of FF. Used both wands and the standard nozzle. The cup is easy to fill and attach, atomization is super impressive, and the speed and coverage compared to aerosol cans is unbelievable- should have started with this from the get go. Just mind you don't kink the wand when spraying - the product will come out elsewhere on the gun, AKA probably onto you while you're laying on your back under the vehicle. Interestingly, I found the overspray with the aerosol cans much worse than with this at 60-80 psi. I attribute that to the aerosol particles being much larger and settling in a small area, whereas out of this sprayer, it is atomized so fine that the lightest breeze disperses it over a much larger area.
