Stop using old fashioned guitar polish, try our nano-ceramic guitar coating! This is not a typical polish; it leaves a microscopic film that flows and levels micro scratches. The film lasts approximately 2-3 years, depending on use. It is perfect for the back of an electric guitar or bass to help prevent buckle rash. The finish looks like glass, hence the name “Liquid Crystal”. It applies very easy; simply rub a very small amount on the instrument with a cloth, let sit for 2-3 minutes, and buff off. It is safe on all finishes including polyurethane, lacquer, varnishes, and paints. One bottle can coat up to 3 guitars with two coats!
