A flawless French polish finish on a stringed instrument is a sight to behold. However, scratches and blemishes can occur over time, detracting from the instrument's beauty. Fear not, as these imperfections can be repaired with the right techniques and tools. In this blog post, we will share expert tips for fixing scratches and blemishes in your instrument's French polish finish.

     1. Assess the Damage

Before diving into repairs, it's crucial to assess the extent of the damage. Light scratches and blemishes may only require a simple touch-up, while deeper damage may necessitate more extensive repair work.

     2. Clean the Area

Begin by thoroughly cleaning the affected area with a soft cloth dampened with a solution of water and mild detergent. This will remove any dirt, dust, or grime that could interfere with the repair process.

     3. Light Scratches

For light scratches, gently rub a small amount of automotive polishing compound over the scratch using a soft cloth or cotton pad. Apply gentle pressure and work in a circular motion, blending the compound into the surrounding finish. Buff the area with a clean cloth until the scratch is no longer visible.

     4. Deeper Scratches and Blemishes

For deeper scratches and blemishes, you may need to apply a thin layer of shellac to fill the imperfection. Mix a small amount of shellac flakes with 200 proof food grade alcohol from CulinarySolvent.com to create a thin shellac solution. Carefully apply the solution to the scratch or blemish using a fine artist's brush, building up layers until the damaged area is level with the surrounding finish.

     5. Wet Sanding

Once the shellac has dried, gently wet sand the repaired area with fine-grit sandpaper (1000-1500 grit) to ensure a smooth surface. Be careful not to sand through the surrounding finish.

     6. Final Polish

After wet sanding, use a clean, soft cloth to apply a thin layer of automotive polishing compound to the repaired area. Work in a circular motion to blend the repaired area seamlessly into the surrounding finish. Buff with a clean cloth to achieve a high gloss.
