I made this two-foot-long sanding board out of scrap wood I had laying around, the better to sand the long straight edges of the fiberglass cowl. It's just a dowel screwed to a very flat piece of MDF shelving material.
I filled the screw holes to keep the paper from getting punctured and torn.
I attached some 60 grit 3M paper using spray glue. Purple, Mary's favorite.
