Electrostatic spray is not new, as most automotive OEM finishes are sprayed this way. The advantage is as much in reducing waste as improved film coverage. My company (PPG) has years of experience in electrostatic applications from dip tank (auto primer), to powder spray (Harley Davidson). The reason they recommend this aerosol can for wrought iron is the charge is so small that it will not "throw" very far on a larger panel. The backbone of a Commando frame may not cover as well.
Electrostatic spray is a big reason why powder coating frames is relatively inexpensive yet thorough. I assure you the charge a powder coater uses on a frame is much greater than what this AA powered unit can provide.
I have located an industrial painter in my area that uses liquid epoxy paint with an electrostatic gun. He is willing to shoot a frame for me at a reasonable cost and I will probably try it on my next project as a more suitable alternative to powder coat. The electrostatic should allow a good film build in tight areas without drips and runs, yet the film would cure hard rather than the plastic nature of most powders.
When my wife re-modeled the kitchen, I balked at buying all new appliances just to match her color scheme. I found a painter to paint the freezer, refrigerator and dishwasher front right in the kitchen with electrostatic spray. Excellent job at one-fourth the cost of new appliances and there was no overspray.
