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

It does work well and it is easy to fill, but the trigger is cheaply made and the hoses ended up coming off the brass nipples and I had to add clamps to keep the hoses attached. Okay, but not great.

I use it to spray undercoating PFC. great gun works perfectly

Great value

first use out of the box and it does not work. gun would not spray at all, tried everything. ive owned a garage for 20 years and have an extensive knowledge of tools. since its been over 30 days i cant return it. dont waste your money.

I dont know why Amazon sells this junk it does not work ! Its a waste of money, might as well light your money on fire ! And if you buy it some crap like this make sure you use it within 30 days otherwise Amazon will not honor their guarantee!

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.

Only problem would be the trigger in soft plastic and in use can be bent so it misses plunger and won’t activate. For the price it is great and allows me to rust proof the frame of my truck.

Nice

Works great without the hoses, but the hoses is where it lacks, tried hi and low air pressure, thinned out the fluid film but to no avail

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.
