Which metal finishing method relies on electrostatic attraction to deposit polymer powder?

Explanation:
Powder coating finishes by spraying polymer powder that is electrically charged while the workpiece is grounded, so the powder is attracted to the surface by electrostatic forces. After application, the coating is baked to melt and fuse the powder into a durable film. This deposition method relies on electrostatic attraction to lay down the powder, unlike the other options: immersion in liquid for dip coating, electroplating which uses electrical current to deposit metal from solution, or baking which is a curing step rather than the deposition method.
