Customers are dissatisfied with the size of the pump sprayer. They mention that the cup is too small for the gun's length of pick up tube, and the aluminum cup doesn't fit snugly.

working well undercoating spray gun

working well undercoating spray gun
This spray gun came in four pieces not including the extra spray nozzles hoses. There were three separate spray nozzles. One hose had a hole to the front and two going outside which worked well in closed spaces for spraying in the frame. The single hole nozzle worked well on open spaces and if I wanted one directly connected to the gun, then the straight nozzle would have closed the deal. I had to connect the 4 pieces together to do the spraying. One thing to note, this sprayer did not come with a coupling for my compressor hose. I had to purchase a coupling at the local automobile parts store. I think it's called an air chuck.

The spray gun itself worked great but could not get it to work with the extention nozzle it only put a thin coating in the hose but never came out the end. Could have been the spray I was using but I did put that in the paint shaker to make sure it was mixed up the only thing I could think was it was too thick to move thru the hose without enough back pressure like the nozzle creates

4.0 out of 5 stars Worked well to apply Fluid Film
Reviewed in the United States on January 16, 2024
Size: with Metal CupVerified Purchase
Worked well to apply Fluid Film. I didn't think it would push the mayonnaise consistency material through the gun, but I was wrong, it sprayed well. I took a star for the 2 problems I encountered. Firstly the trigger slips/twists off the little valve pin it sits on. So there were a few time I pressed the trigger, and it slipped off the pin, making me think I broke it. Secondly, the clear hoses, for getting into the frame and such, are just pushed onto the brass fitting. I had them pop/pull off a couple times. I will have to add small clamps on there. Overall, for a gun I plan to use a couple times a year, it worked great. If I was planning to use it more, I'd probably look for a better gun.

3.0 out of 5 stars FRUSTRATING BUT FUNCTIONAL
Reviewed in the United States on August 18, 2022
Size: with Metal CupVerified Purchase
Picked this up to spray Corrosion Free (an oil based undercoating gel) on my truck. While it worked, I found it very frustrating to operate due to 3 issues:

1) The trigger has a ton of play, and it often slips off the plunger that actuates the airflow. Especially in the least convenient and comfortable times working on your back under a vehicle.

2) The wands do not have any clamps holding the hose on. This is easy to correct but quite silly that we have to.

3) The jar doesn’t really lock on positively. There’s three posts on the jar and three slots on sprayer. Once everything gets greasy as it inevitably does, the jar will slip past the detents and come loose as you are attempting to tighten it. There is a sweet spot but again, frustrating.

But here’s the deal. The nicer gun and wand combo here on Amazon is $100. I guess I’m willing to deal with some poor design and save the $60. Because really, this is used once a year. And aside from the design snafus, it does work. I got rid of the regulator and used the one on the tank set to 90 PSI. Less bulk. I also fitted a swivel connection to improve maneuverability in tight spots. All told, with the tweaks it works okay. But it is a cheap tool and not great.

I used it with my small 6 gal pancake compressor and it did take a little longer letting the compressor catch it’s breath between applications. But it goes to show you don’t need something huge and expensive to do this yourself! I am also pleased with the Corrosion Free and recommend it.

1.0 out of 5 stars I got what I paid for :(
Reviewed in the United States on October 28, 2022
Size: Threaded for Metal CansVerified Purchase
Cheaply made, frustrating, messy. The plastic trigger is so loose on the retaining pin that it goes to the side and slips off the trigger pin so you can't spray unless you pull it perfectly straight with no side pressure at all, very hard to do. I was able to fix that but taking the pen out and putting a very thin plastic shin in the trigger to tighten it up, but we shouldn't have to do that.

Worse, If there's any back pressure from the extension nozzle at all, the pressure goes into the bottle instead, and pops it off the inadequate screw threads, making a huge mess. Since it didn't even come with the metal screw on bottle, I had to resort to using an HDX bottle from home depot, but of course the plastic threads slipped off many times resulting in a huge mess and waste of expensive rust proofer. Good luck finding an aluminum screw on bottle - the only one in Amazon is the SEM 71004 SCHUTZ bottle for $18.

The plastic tube extension nozzle that comes with it is so loose on the brass fittings that it pops off easily, again making a mess. I had to put hose clamps on both ends to keep it from falling off. Finally, it is completely non-adjustable, the little dial on the so-called regulator just turns it on or off, even if you screw it all the way out it doesn't get any more powerful. I wish I had just spent the extra money to order the real brand name one.

It works to spray wool wax on my frame. as part as rustproofing and works fine. Long term I do not know. However, concerned the plastic handle will break and aluminum bowl contacts will wear out. Also barbed fittings for plastic tube need a hose clamp, otherwise plastic sleeve pops off. That is easy to do. Need to check if they have replacement parts otherwise may return.
