After I had the winch apart I went to work scrupping it with a wire wheel attached to a drill, and my Q-tips and tooth-picks.
The Drum before and after I had taken a wire wheel to it. After I cleaned it I coated it in POR-15. I chose the POR because it goes on rock sold and smooth like glass. I wanted a smooth finish like that for the 5/16" x 125' Master Pull synthetic rope line to attach to.
