I’ve been using a blackboard eraser to do final dressing on my frets. I take this nice soft eraser and a piece of 600 paper and go across the fretboard. It’s beautiful; it just follows the curve and gives you a nice even rounded top. This is for polishing, after you’ve shaped the frets with files. ◆
