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

Did not siphon the fluid film properly. Cheesy plastic trigger. Took 3 times longer than it should to do the job. Got frustrated and tossed it in the trash.

I bought this specifically because it had an extension wand so i can get to the wheel wells in the bed of the truck. If anywhere this is the worst place on trucks. I cant get the Fluid Film to go through no matter what pressure its set at. As a matter of fact the material comes out the air hole in the top of the gun. It is back-feeding the air into the can. Im trying to find a solution to this because I need to get to this area. Id be curious to hear about thicker undercoatings working with this extension.

Used the 360 degree tip. Paint delivery was better than expected so line pressure was reduced down from 50 psi. 35 psi worked well for the paint thickness consistency. I didnt need to use the straight tip for my project.

This product works great. I sprayed the underside of my Ford Excursion and Edge with hot Fluid Film, and it works fine for the task and price. The extension hoses are a little rigid, but they still work just fine. Make sure you use thread tape on the air fitting connection for no leaks.

Worked ok. Make sure temperatures are warmer so the thick liquid flows smoothly. Above 75. Its a messy job but well worth it. The colder the temp the higher the pressure at the gun.

Was very impressed with this purchase. I sprayed the frame of my Truck with this unit and it worked great. I dont do it for a living but for my needs it is great.

Undercoating

The spray gun would not stay closed, the extended nozzle kept blowing off getting product all over and made a huge mess. I am so disappointed in this. do not buy this. Try to find a different spay gun.

sprayer works well but the plastic trigger needs a bigger surface area for the pin to be pushed. it will easily push to the side and not spray. tape and/or epoxy will help.

These cost about half of the main brand but worked surprisingly well. It sprays well out of the extension tubes into the frame and tight spaces. The trigger handle is soft and bends, thus missing the stem. It is best to push it near the hinge, right on top of the stem. I used it with used transmission fluid so far.
