Abstract
A system for removing scratches from glass windows, windshields and the like utilizing a compound applied to a powered polishing disk/pad which effectively “scrubs” away the scratches. Liquid needs to be applied during the process. To enable the operator to use both hands to maneuver the tool while also controlling the liquid application procedure, a hand piece is mounted to the tool which functions both as a second handle for the operator and also places a finger/thumb actuated liquid spray control accessible to the operator. A nozzle connected to the control and receiving liquid from the control is mounted for directing spray onto the glass surface outboard of the periphery of the pad.
