Overall I found the easiest way for me to deal with the special problems with powder paint was to use an air gun. I heat with an adjustable temp heat gun and use forceps to hold jig. The gun I use is made by Badger and it was made to actually be a mini sand blaster. Works with a less than 10 psi compressor.
This method is extremely messy unless you set up a cardboard booth with vac attached. The problem with dipping jigs in powder paint is that you almost always get too much paint on it. I never had any luck even with the fluidizing beds. Spray painting with powder paint is NOT the fastest way to paint but it allows you the most creativity.
Most important to me is that when curing I do not have to take any special pains to hang them. All the jigs come out looking just like when they went in. No runs no drips and no errors..
Spray painting with powder paint does require patience. Depending on color the gun will clog easily. I hold my finger over the opening and back pressure into jar and it clear 90% of time. Other 10% of time I have to remove jar that holding paint and run a small wire up through the line to the trigger. This method would not be advantageous for a commercial operation. Although they do make systems that would be. But the investment would be a back breaker for the hobby guys like most of us are.
One other piece of advice if you decide to try spray method . Get plenty of extra jars. I label the color on side of jar and can change colors in a matter of seconds.

The link above has a tutorial on using this method. I use his gun that he sells but do not care for his compessors.
