Top tier high quality tool at an extremely affordable price

Excellent sprayer used for fluid film amongst other underbody coatings works great have no issues with it makes life a whole lot easier plus you have the extension hoses to get inside the hard to reach areas definitely a win and worth every penny

Works good for frame maintenance.

Works good for spraying por 15 rust destroyer. Works ok for Fluid film. The straw seems to clog some, but otherwise, it’s really good.

The gun is pretty much trash.

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.

This works great once you make the modifications I mentioned.

This product has some design flaw issues. It did work very well when I made some modifications. The canister kept falling off spilling my under coating. It would not stay locked on. I bent the ends on the lid which solved the problem of it not staying locked on. Then the hose would fly off they do not stay attached. A person will need to put a small hose clamp on the hose so it will not blow off. If you address those problems then it works great. But I lost a lot of undercoating before I realized I need to make some modifications.

Buy it nice or buy it twice

Used this gun on about 8 vehicles so far. Just like all the other reviewers say:* Cup does not have a positive lock which can cause it to become uncoupled from the gun.* The extension hoses do not provide good coverage and/or pressure in order to reach inside of cavities, frames, and the like.* The extensions pop off the barbs causing frustration.* Wobbly trigger that needs to be pressed “just right” for the gun to spray.Overall if you are planning on using this tool more than once in your life I would probably pay up for something better. I may try and make some modifications to this gun in order to improve it, unsure yet.Two stars given for the fact that it does actually spray pretty decently without any of the wand attachments installed.
