Professional high gloss polishing: ColorTone Buffing Compounds remove fine scratches from finish topcoats, metal, and plastic surfaces. Designed specifically for musical instruments These new formulas will give your instruments a professional shine for a showroom grade high gloss finish. ColorTone Buffing Compounds remove more scratches than automotive compounds (the industry standard), and were specifically designed and tested to achieve the stunning mirror finishes found on high-end guitars, mandolins, and other musical instruments. Used in conjuntion with a buffer, they're ideal for polishing pickguards, bone nuts, wooden bridges, frets and other metal parts too. Great value, less waste: 24-ounce buffing bars are smaller than most, but still plenty of compound for years of use in both factories and small shops. Important: use separate buffing wheels for each grade of compound.
