I'm a big fan of powder coating small parts, but it becomes a huge PITA when doing one-off individual parts of different colors.
So I decided to try using a small airbrush-type sandblast gun I have, along with heating the part with a heat gun. The amount wasted powder is minuscule, considering there is no electrostatic charge apparatus.
In a nutshell, heat part with heat gun, spray powder on, heat and spray repeatedly to desired coverage. Works perfectly. No powder gets blown off by the heat gun using this technique.
Below is pic of a lathe cutoff I picked up and tested this on, so quality was not a concern.
