Just fixed one used 240/340/600 grit sandpaper, put sheet of sandpaper on a flat surface, put pipe rim on sandpaper , go in a clockwise direction keeping pipe flat, work up to the other grits, I wiped mine down with everclear, took small spoon of 3 way tool and mixed lt brown and small bit of cordavon lit it up , melted shine, took q-tip and applied, ran butane lighter lightly on polish , then wiped it off. One cost did the trick , you"ll have to guess the color of pipe for mixing polish,it wasn't" hard , but keep in mind you can only go so far and you will lose the shape of the pipe. The old cajun
