Review on TCP Global 9-Piece HVLP Spray Gun Set - Includes 2 Full Size Spray Guns, 1 Detail Spray Gun, Inline Filter, and Air Regulator by Mark Bennett

First things first, as others have written, the first thing to do is disassemble the nozzles and clean them thoroughly. Use a wire brush to scrape off the crappy white caulk they used to bond them together. There will also be some oil. They work flawlessly and the controls are as expected from an entry-level product. I'm upgrading the siphon sprayer that came with my first set of air tools that I bought at the Orange Big Box store. This is a HUGE upgrade over this weapon. My only complaint and the reason I don't make this a five star product (other than having to disassemble and clean them first) is that they put a 0-180psi gauge on the kit. Don't they understand that the "LP" in "HVLP" stands for "low pressure"? If you are using these guns at around 10psi and trying to set that pressure on a 0-180psi gauge your pressure will not be accurate. After a few uses I changed it to 0-30 and now I have a lot more confidence in my output pressure.
