and where the two arms are angled upward in directionally opposing fixed relationship to one another where one arm is angled upward and forward and the other arm is angled upward and rearward relative to one another such that the two horizontally aligned spray heads are also vertically offset from one another to produce two paint spray fans that overlap one another, but that do not collide with one another by producing paint spray fans that spray in different parallel planes. ### Claim 6 (depends on 5) The method of claim 5 where the paint spray fans overlap by 40-50 percent. ### Claim 7 (depends on 5) The method of claim 5 where the spray heads are paint spray assemblies separated from one another across the length of the dual paint spray wand by a predetermined distance. ### Claim 8 (depends on 5) The method of claim 5 where the spray heads are separated from one another across the length of the dual paint spray wand by 3 to 8 inches. ### Claim 9 (depends on 5) The method of claim 5 where one spray head sprays ahead of the other when painting a surface. ### Claim 10 (depends on 5) The method of claim 5 where each of the two arms has a spray end having threading for receiving the spray heads. ### Claim 11 A dual-headed paint spray wand for connecting to a paint sprayer, where the spray wand has-a length and width and a central feed tube having a central longitudinal axis for receiving paint from a paint sprayer, where the central feed tube is split into two arms each having a spray end where the two arms are separated at a predetermined distance from one another, where the entire length of each arm is rigid, non-articulated, and is fixedly attached to the central longitudinal axis of the central feed tube with one arm positioned on each side of the central feed tube and where the two arms are angled upward and in opposing fixed relationship to one another, such that one arm is angled upward and forward and the other is angled upward and rearward relative to one another such that the two spray ends are also vertically offset from one another to produce two paint spray fans that overlap one another, but that do not collide with one another by producing paint spray fans that spray in different parallel planes. ### Claim 12 (depends on 11) The wand of claim 11 where the predetermined distance between of the two arms along the length of the dual-headed paint spray wand is between 3 to 8 inches and where the vertical offset of the two spray ends along the width of the dual-headed paint spray wand is between ½ an inch to 5 inches. ### Claim 13 (depends on 11) The wand of claim 11, where each of the spray end includes a spray head for spray paint. ### Claim 14 (depends on 11) The wand of claim 11, where each of the spray ends include threading for receiving spray heads for spraying paint.
