I was gonna take off some stars in the beginning, because of poor assembly instructions, they're BAD... but after the learning curve, and using the item, the machine is actually fantastic.
The assembly instructions are terrible. Go on YouTube and search [WX-958] to get the machine put together & up-and-running.
I've never powdercoated before. This was my first time. I am skillful construction guy though, so I figured things out pretty quick. Make sure your fluidizing hopper bottom feed air is always less than the gun's air. Hopper air @ .03 worked best for me. Rinsing air @ .5 worked good, Gun air @ around .6, and Powder was usually around .7 for me.
We just bought dump truck, and the wheels were the only thing that needed some attention. I've been watching powder coating videos for 20 years, and I was always fascinated by the process. I decided to try out some powder coating as a winter project, but I didn't want to spend 5,000 dollars on a Gema, Wagner, or Nordson setup.
The WX-958 performed just like a professional expensive setup, at 1/10th the price. Here's a warning though, this is an industrial-level setup, with an industrial-sized hopper. So, unless you plan on purchasing and spraying 25lbs of powder at a time ... the hopper it comes with will be way too large to get proper powder pick-up for the average small-time hobbyist user. You'll have to buy an additional, small, 2lb fluidizing hopper to get powder flow. You can find them for around 70 dollars. Under 500 bucks total, for a professional powdercoating result is amazing, and unheard of. I'm very happy with my first powder-coating experience, there will be many more to come.
The powder coat I used is called SuperChromePlus from Prismatic Powders. It was about 25 dollars a pound. To powdercoat 6 huge 22.5"x8" dump truck wheels, I used about 3.5--4lbs of powder, maybe less.
