Probably something I'm not doing right. I made some fluid beds and they didn't work. The powder paint just got holes in them, volcano I think it's called. I bought 2 from a supplier, recommended on here. They do the same thing. I've tried more air, less air, shaking, more powder paint, less powder paint, lot of bad words but all l get is more paint on my hands, clothes and in my shop. I'm using Pro-tec powder paint. Have tried several colors. What's the trick? Thanks, Don
I made some several years back. As I remember there is a fine line between volcanos and the point where the powder with act like a fluid. I got there using pneumatic flow controls. It allowed a more precision control over the air volume
Less flow on beds and longer time to fluidize. Patience my son.
How many fluid beds are you trying to run at one time? Everytime time you add a fluid bed to the same air pump. You will need to keep adjusting the air pressure to the previous bed. Because your lessing the air pressure to the bed that you already set. Probably takes me 10 or so minutes to adjust my beds. With a few tweaks after I start powdercoating. I also have to give each bed a good stir when I first turn on the air to the beds.
If drop a jig and it sinks to the bottom of the bed. That's s a good starting point of fluidity.
Here's a great video..

I love watching Mark Rober on YouTube. Good video thanks for sharing
Also, try thinning your paint with clear.
I only run one fluid bed at a time.
Paints are all different as far as texture too,,,some is really easy to use and others seems to be clumpy if you don’t mix it well or use enough air,,,very touchy stuff,,,
You can also add clear to the color to help flow better and get more mileage out of your colors.
What brand of paint are you using? I agree about the clear. anything from harbor freight needs thinned.

I bought a dental vibration machine and run the cup on top. It keeps the power moving and was only about $50. You can adjust the vibration intensity. Just make sure you attach the base to the vibration plate so it doesn't shake off and dump the powder everywhere.
Is this the clear that everyone's recommending? Attachment 424692
You can get quality automotive clear powder paint for much cheaper. I’ve used this from thepowdercoatstore.com for several years with great results:
