To brush paint the car wouldtake one man three or four hours. While spraying this carwill require 11 gallons of paint as against 9 gallons appliedwith a brush, one coat by the former method is equal to twoby the latter.

When painting along the top of the sides, somepaint spray may go over the edge of the roof boards, butthis paint falls on the roof and therefore is not wasted. The
