b. a flow trigger; c. at least one positioner engaging the member and adapted to maintain a spray tip in a desired position relative to the member; d. a mounting means for releasably engaging the spray tip assembly around the member; e. a coating supply fluidly connected to the spray tip and a flow activated by the trigger; and f. the spray tip assembly calibrated to provide complete radial coverage of the member, whereby an user engages the positioner placing the apparatus around the member and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass. ### Claim 2 (depends on 1) The apparatus of claim 1, where the handle may be rotated. ### Claim 3 (depends on 1) The apparatus of claim 1, where a positioner is a roller. ### Claim 4 (depends on 1) The apparatus of claim 1, where a positioner is adjustable. ### Claim 5 (depends on 1) The apparatus of claim 1, where the mounting means includes an opener having a release which, when activated biases the apparatus into an open position, the force for biasing from a group consisting a spring, rubber band, hydraulic, and pneumatic. ### Claim 6 (depends on 1) The apparatus of claim 1, where the mounting means includes a closer having a latch which, when activated biases the apparatus into a closed position, the force for biasing from a group consisting a spring, rubber band, hydraulic, and pneumatic. ### Claim 7 (depends on 1) The apparatus of claim 1, where a recapture tray adapted to collect and retain excess coating from overspray and drips whereby some can be recycled the spray tip assembly may be rotated. ### Claim 8 (depends on 1) The apparatus of claim 1, where a coating volume flow rate control adapted to provide a desired amount of coating to the members while reducing overspray and dripping. ### Claim 9 (depends on 1) The apparatus of claim 1, where a coating volume flow rate remains constant through the adjustment of spray tip assembly. ### Claim 10 (depends on 1) The apparatus of claim 1, where the spray tip assembly does not fully enclose the member adapted to provide complete radial coverage. ### Claim 11 (depends on 1) The apparatus of claim 1, where the spray tip assembly may be rotated. ### Claim 12 (depends on 1) The apparatus of claim 1, where the spray tip assembly consist of at least one spray nozzle. ### Claim 13 (depends on 1) The apparatus of claim 1, where the spray nozzles may be adjustable to a wide or narrow spray pattern. ### Claim 14 (depends on 1) The apparatus of claim 1, where the spray nozzles may be calibrated individually to provide even flow rates around the entire circumference of the spray tip assembly. ### Claim 15 (depends on 1) The apparatus of claim 1, where the spray nozzles may be calibrated in groups to provide even flow rates around the entire circumference of the spray tip assembly. ### Claim 16 (depends on 1) The apparatus of claim 1, where the spray tip assembly setting may be selected from focused spray pattern for spraying in windy conditions and a dispersed pattern for calm conditions for better coverage. ### Claim 17 (depends on 1) The apparatus of claim 1, where the spray tip assembly has a windshield attached to enable use in high wind conditions. ### Claim 18 (depends on 17) The apparatus of claim 17, where the windshield is adjustable around the member. ### Claim 19 An apparatus for coating an elongated member comprising: a. a handle b. a flow trigger c. a positioner d. a closed mounting having— i. spring biasing the mounting in the closed position ii. an opening lever forcing the mounting open for releasably engaging the spray tip assembly around the member; e. a coating supply f. a spray tip assembly having— i. an inlet fluidly connected to a flow trigger ii. a plurality of spray nozzles inwardly spraying and radially positioned to provide full coverage of a member, whereby an user opens the mounting, places the apparatus around the member and engages the positioner, releases the mounting and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass. ### Claim 20 An apparatus for coating an elongated member comprising: a. a handle b. a flow trigger c. a positioner d. a open mounting having— i. spring biasing the mounting in the opened position ii. a closing lever forcing the mounting closed for releasably engaging the spray tip assembly around the member; iii. a latch for maintaining the mounting in a closed position e. a coating supply f. a spray tip assembly having— i. an inlet fluidly connected to a flow trigger ii. a plurality of spray nozzles inwardly spraying and radially positioned to provide full coverage of a member, whereby an user places the apparatus around the member, engages the positioner and closes and locks the mounting in the operational position and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass. ### Claim 21 An apparatus for coating an elongated member comprising: a. a handle b. a flow trigger b. a roller positioning the spray tip assembly d. a fixed mounting having an opening for releasably engaging the spray tip assembly around the member; e. a coating supply f. a spray tip assembly having— i. an inlet fluidly connected to a flow trigger ii. a plurality of spray nozzles inwardly spraying and radially positioned to provide full coverage of a member, whereby an user engages the positioner placing the apparatus around the member and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass.
