Abstract
An improved method and apparatus is disclosed for sequentially electrostatic spraying different ones of a plurality of electrically conductive paints from a plurality of paint sources. Each paint source is connected through a separate electrically non-conductive first hose to a manifold and then through a single second hose to a spray gun. After spraying, at least the first hose which carries the sprayed paint is purged of paint and dried to electrically isolate the source of the first paint from the manifold when a second paint is sprayed.
