At StewMac, our finishing supplies offer everything you need to achieve a professional-level guitar finishing result. From grain filler and sealers, to stains, translucent dyes, and opaque lacquers, all the way to the final clear coats, our products help you bring out the best in your wood and create stunning custom finishes. For the right tools and materials to support your finishing work, explore our full range of finishing tools.
Comprehensive Finishing Kits and Products
Our finishing supplies include specialty abrasives, polishing compounds, dyes, pore fill, and traditional or modern finishes designed specifically for guitars. Whether you want a modern high-gloss, a reliced vintage look, or a subtle matte finish, our range of products lets you control every stage of the finishing process.
Plus, our ColorTone supplies cover it all—from concentrated liquid stains and translucent dyes to nitrocellulose or water‑base lacquers (in aerosols and bulk), along with pro‑grade polishing and swirl‑removal compounds and handy drop‑fill touch‑up markers—so you can spray, tint, or spot‑repair with the same gear trusted on custom‑shop builds.
Traditional Finishes and Aerosols for Professionals and Hobbyists
Whether you’re running a full spray‑gun setup with a compressor or shaking up an aerosol can in the garage, StewMac makes it easy to lay down a factory‑grade finish. Our nitrocellulose lacquers and metallic paints come in both bulk quarts for professional spray rigs and perfectly‑tuned aerosol cans that atomize evenly, flash fast, and build to a mirror‑smooth film—no expensive equipment required. Grab a can, pull the trigger, and get the same depth, clarity, and durability the pros swear by.
Looking to start from scratch? Pair your finish of choice with one of our acoustic guitar kits or electric guitar kits and roll straight from assembly to spraying—every component is spec’d to take lacquer beautifully and show off your custom colors on stage or in the studio.
