Powder coat plastic?

Powder Coatings:

“Polyester powders are thermosetting resins that are applied electrostatically to a steel surface and heated to temperatures around 180oC (=356o Fahrenheit). This technology produces very uniform coatings that have an attractive architectural finish with excellent atmospheric weathering characteristics. The powder coated product ensures maximum durability for steel components, which will generally provide 50 year+ rust free life spans in most architectural applications.”

So IN THEORY, it should be possible. Many non-metals will hold an electrostatic charge (rub a balloon on wool and watch it attract your hair). Whether this charge is strong enough compared to a metal with current running through it is questionable. Furthermore, it must be a plastic which, not only holds a charge, but does not deform at 356o. Tough to find.
