Abstract
An improved method and apparatus for applying a multicomponent coating composition onto a substrate. The method comprises separately transporting at least one component under pressure to a proportioning device which provides a controlled ratio of the components. The components of the coating composition are then mixed and coated onto the substrate at ambient temperature or, to accelerate curing, at moderate temperatures. The method is especially useful for applying multipackage refinish coating compositions.
