I purchased this product after seeing videos recommending it for woodworking in difficult areas. I had to sand the old finish. It definitely wasn't enough for that. It's rubber! So it was like trying to remove a finish by deleting it. In addition, it wore out very quickly. I may have selected the wrong product for my needs, there are many very good reviews. But I'm not happy spending $30 on it. I'm stuck with a bag full in case anyone wants them!
