This is my blend of French polish, adequate for varnishing guitars by hand. I always found myself unsatisfied with the viscosity of what was on the market. Moreover, French polish should be made of only 3 basic ingredients, and no need for any additional chemicals that I see often on popular brand labels.
After several iterations, here is the Atelier's concoction for you.
All-natural ingredients: Shellac resin, alcohol, and hardening oil.
Direction: Apply polish on a cotton ball, wrap it in a lint-free cotton rag. Rub the wood surface lightly several times until the desired level of shine is achieved. Change cotton and cloth regularly.
Warning: Keep away from children. Keep sealed when not in use. Do not ingest.
