Classical guitars have delicate finishes, which are easily damaged by fingernails. Guitar Armor protects the finish on your guitar without requiring any adhesive because it is made from static cling vinyl. Apply Guitar Armor before playing your instrument and remove after practicing. You can reuse it over and over again.
When applying Guitar Armor, leave a slight edge overhanging the soundhole so it can be removed without having to insert a fingernail under the the static cling vinyl to pull it off. Not recommended for instruments with new finishes.
