No comments The finish is sprayed on Gino’s guitar. By mark_admin • October 28, 2013 Uncategorized I sprayed 12 thin layers of a water-based lacquer called KTM-9. It cured for 10 days before I buffed out the finish to a nice gloss. The neck and body after six coats. The top after ten coats. A close up of the Paua Abalone rosette.
