Just finished overhauling the insides of my gorgeous GF-777 - new belts, new pinch rollers, new heads. After a thorough cleaning and calibration, it sounds AMAZING. the only things left are a body-related - there are few scratches and dings across the top - unfortunately in the most visible places. What do folks do? Sand / repaint? I'm worried to touch it - appreciate any recommendations. thanks and hello from Illinois!
