Powder coating: way to add more positive charge?

[stryped]

TL;DR Summary

Powder coating

I am thinking of powder coating at home. I know the part to be coated is negatively charged because it is grounded. I assume the powder is positively charged by the gun. I wonder if there is a way to add more positive charge cheaply to an inexpensive gun like the one at harbor freight? I think this is one of the drawbacks of a cheaper made gun. Could some sort of static charge be added?

I use to work in a powder coat factory, spray on powder is thermoset plastic. Hot oven melts plastic to clean metal parts. You can order powder any bake temperature you like. I think the lowest bake temperature is about 350°f. We used 540°f power. Metal parts are electrically charged + & - to make powder attracted to parts. Call PPG they sell powder, they will mail you 1 lb free samples. House is none conductive how will you make powder stick and how will you bake your house in an oven? Heat gun will take years.

The cascade is located in the barrel of the pistol. That will determine the voltage you get out. Simply install a more powerful one, up to 140kV.
