Polishing Drum Clearance Stock These polishing drums were unfortunately left in the sun too long during transport and the glue that holds on the working layer was weakened. We want to clear this stock so we are offering these drums and a bottle of glue to attach the working layer at a special one-time discount! Simply use the included bottle of glue to attach the working layer and hold it in place for two minutes while the glue dries….then you will be good to go. Other than this glue issue, these items are still perfectly fine and quality polishing drums. We have drums in a variety of different grits for all of your polishing needs.
