TCP Global Air Rust Proofing and Undercoating Gun with Gauge & Suction Feed Cup, 2 Wands - 22 Long Flexible Extension Wand with Multi-Directional Nozzle - Spray Truck Bed Liner, Rubberized Undercoat

Finally Found an undercoating gun that did not clog up

You definitely get what you pay for. It will do the job. But if you were going to do and lotta vehicles, this probably wouldn’t be a gun to buy. The hoses are definitely convenient to get in all the nooks and crannies.

Gun works well applying LPS3 under my truck. Needed both hoses to spray nooks and crannies and inside boxed frame. Two small problems; trigger slipped sideways off plunger, gun with gage is a little too long if truck is not on lift or ramp. Found ways around those problems.

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.

Works great I spray Fluid film and oil to undercoat my cars.

Made in. Hina cheap works but zero quality

Air adjustment on gun. Made job go fast.

ok

The wands included continually come off. They are not held on in any way, just shoved in the wand. This causes fluid film to go everywhere. The wands are very stiff and come in a coil shape. The trigger does not line up well with the actuator causing frustration when your under a vehicle and your struggling with an oil soaked gun that wont spray.

The gun worked moderate. I have used worse siphoned style guns . Trigger was loose out of box, it moves around during use and causing the needle not to push in . For a newbie doing anything with this gun is not suggested.. I was able to finish the job and keep things from setting up or pooling.. and now for them spraying hoses.. thats crapp.. unless you use pure cleanup laquer thinner.. there is not enough siphon with 30 psi and spraying undercoating or bedliner materials through them.. .
