Good article Johnny, but I didn't see any mention of it being used on plastics or composites, only metal. From the article: "Coating producers will have to provide everything from the metal cleaning and pretreatment to the final topcoat.".I found this article from 2006 about powder coat painting. It even mentions the shreveport plant.

I had no idea powder coatings had been used in the auto industry by so many, for so long.
