Guitar Building DVD

Guitar Finishing With Water-based Lacquer

Finishing with Water Base Lacquer

A three hour, two DVD set made for first time guitar finishers using water-based nitrocellulose lacquer. This DVD set will show you how it is possible to achieve a great finish in your home workshop. Basic finishing skills and knowledge are required. Easy to use, much safer than solvent based nitrocellulose lacquer, water-based lacquer cleans up with soap and water. The DVD set covers application with a brush, foam roller and spray-gun. Instructor Jamie Boss covers everything needed to finish your first guitar with great results. Filmed at my guitar building school in Milford, Connecticut, the entire process is broken down to each individual finishing step with close-ups and instructional graphics. Water-based nitrocellulose lacquer dries quickly, has practically no smell what-so-ever, is non-explosive and provides a deep finished shine after final buffing. This finish can be easily applied in the home workshop with a minimum of problems. You can find additional information about or purchase water-based lacquer at and
