The easiest way to spray a professional finish! ColorTone® Aerosol Guitar Lacquer produces a beautiful traditional Nitro lacquer finish, without elaborate spray equipment, and is formulated especially for musical instruments. Fast-drying and resistant to alcohol and water, it produces a hard, durable finish that enhances the beauty of the wood. ColorTone lacquers can be applied over smooth bare wood, sanded basecoats of grain filler, ColorTone Sanding Sealer, and over ColorTone Stains. Perfect for touch-up work, or for finishing an entire instrument. ColorTone Sealers have a high solids content and provide excellent adhesion for lacquer topcoats. For opaque finishes, refinishing projects or oily woods, choose the moisture-resistant Vinyl Sealer for the basecoats. For spraying a transparent finish, we recommend Sanding Sealer (sold separately) as a base, followed with ColorTone lacquer. ColorTone Sealers are flexible and compatible with many different finish types. Do not exceed more than 2 coats of sealer. 13-ounce spray can. How many cans do you need? Electric guitar neck: 2 to 3 cans lacquer (no sealer needed) Solid body electric: 1 can sealer + 3 to 4 cans lacquer Acoustic or archtop guitar: 1 can sealer + 4 to 6 cans lacquer Mandolin or dulcimer: 1 can sealer + 3 to 4 cans lacquer Banjo rim and neck: 1 can sealer + 3 to 4 cans lacquer Ukulele: 1 can sealer + 2 to 3 cans lacquer Number of cans needed may vary depending on how heavy the coats are applied, number of coats, and desired thickness on your instrument. Use warm lacquer, not cold! Pro shops spray heated lacquer because cold lacquer spatters, requiring extra sanding. You should warm up your aerosol lacquer too, simply soak them in a sink of warm tap water. We recommend spraying multiple thin coats, in a low humidity environment.
