Beautiful Guitar Finishes Start with the Right Products

Finishing a guitar correctly is essential. The right finish not only enhances the instrument's appearance but also maintains the natural resonance of wood, ensuring clarity and richness in tone. As you can see from Michael's guitar, the results speak for themselves by using Aqua Coat's Clear Grain Filler and Instrument Lacquer.

Whether you're building your first guitar or you're an experienced luthier, Aqua Coat offers products designed specifically for instrument finishing. Our grain fillers and lacquers are trusted by guitar builders who want professional-quality results with a smooth, beautiful finish.

Aqua Coat Clear Grain Filler helps achieve a clear, glass smooth finish on hard to fill woods. This small particle size grain filler penetrates and seals the pores minimizing the absorption of your topcoats, achieving a glass, smooth, clear finish in less coats. It can be used before or after staining.

Aqua Coat Instrument Lacquer is a premium water‑based acrylic/urethane blend engineered to deliver a flawless finish and superior protection. Its self‑sealing formula provides exceptional toughness, flexibility, durability, and hardness—offering long‑lasting resistance to marring, heat, scratches, and moisture.

Give your next guitar project the finish it deserves with Aqua Coat.  Aqua Coat's water-based products are easy to apply, dries fast, sands easily, nonflammable, low VOC and water cleanup and a safe alternative to traditional oil-based products.
