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

Works great.

Very cheaply made but it’s a fair product for a great price. Trigger is plastic and very chinsy. The 360 degree fitting with hose is okay but sprays more of a stream out of each of the 4 holes rather than a mist when using Fluid Film. This can be compensated for by turning the hose different directions to get somewhat adequate coverage. I will say this gun when using the standard spray tip does an excellent job and really lays the product down quickly.

I bought this specifically instead of the ones with the plastic screw on bottles because I thought the all metal construction would be more durable and also because it looked like it would fit easier into tight spots with a container that doesn't hang down as low. Unfortunately, the quality is absolute trash. The connection between the tips and hoses leak like a sieve because they are just loosely slid into the hoses with no seal or clamp whatsoever. The multi-directional nozzle also barely sprays any product, basically making spraying inside cavities impossible with any sort of coverage. Also, the biggest flaw is the product cup doesn't screw on. It just lightly twists on with three little soft aluminum tabs that friction fit into little grooves. These tabs basically completely wear flat after about half a dozen turns leaving the cup with no way to tighten. This results in the cup constantly falling off and spilling product everywhere. Don't waste your time on this thing. It is pretty much worthless. Just do yourself a favor and buy the other style with the plastic cups that actually fully screw on tight.

Works good!

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.

Excellent gun

This was enticing because of the extra wands and metal cup plus an adjustable intake gauge, but....it's cheap. Don't over tighten the cup, or it will basically slip off every time, the gauge air adjustment is either on or off, so you need to set your compressor. The wands are nothing but barb fittings, so they come off whenever they please. I blocked the center hole in the fan tip so it would actually spray a fan pattern. Worst of all was the trigger. It only has the smallest surface to depress the air valve, and, as you use it the trigger can flex, side to side and no longer hold the valve in. You have to reset the trigger, pull again, and spray. Then it slips again. Very poor trigger design. Why 2 stars you may ask? Well, I did end up coating my truck. It applied product to most surfaces, so I guess, for a cheap sprayer, it works.

This was a great purchase, great value and came exactly as described, No regrets at all and highly recommend. Used it for Coroseal that is a rust inhibitor for inside and outside my truck frame.
