ABSTRACT:
A spray assembly including a venturi type spray nozzle, a valve attached to the spray nozzle, a reservoir adapter that can engage a reservoir containing a liquid coating material to be sprayed, and a flexible hose between tile reservoir adapter and the valve. The outer surface texture of material being coated can be adjusted using the valve which is useful in matching the surface texture of chip resistant coatings and undercoatings on an automobile, and the hose allows the operator to spray material onto a substrate from any orientation of the spray nozzle which facilitates coating locations such as the lower portions of panels or in wheel wells and trunks. A valve passageways is shaped to facilitate fine adjustment of the air/coating material ratio when small amounts of material are being delivered, and the valve includes an air purge to remove material from the valve and nozzle when the valve is shut off.
