How do you seal a Sharpie on a guitar?

Spray a fine mist of acrylic clear coat over the autographed area. One coat of the protective spray will work fine. Allow the clear coat to dry before playing or moving the guitar. If the guitar has already been signed with a permanent marker or sharpie, use a clear nitrocellulose lacquer to preserve the signature.
