Things You'll Need
Instructions
Buff the scratches or nicks gently with the liquid scratch-remover, applied with the soft cloth. For minor surface blemishes, this may be all you need to do.
Use clear nail polish or wood filler, depending on the guitar's surface color, on any pitted areas or light surface cracks that are too deep to be removed by the buffing procedure. Apply the polish or filler carefully in the scratched areas only. Allow it to dry completely.
Use fine sandpaper to gently sand the dried polish or wood filler until the surface is smooth and even with the rest of the guitar's surface.
Apply matching guitar lacquer to the repaired area. Allow it to dry completely.
Seal the lacquered area with a sealer especially designed for finishing guitars. Once the sealer is completely dried, buff the area with a soft cotton cloth until it shines like the rest of your guitar.
