Woodworkers cannot identify existing furniture finishes before refinishing, leading to failed restoration attempts

Furniture owners and woodworkers struggle to accurately identify what type of finish (lacquer, varnish, shellac, oil, etc.) is on existing chairs and detailed pieces before attempting refinishing work. Without proper identification, they apply incompatible products that result in poor adhesion, peeling, or ruined finishes, wasting time and materials. Current solutions rely on trial-and-error testing or expensive professional consultations.
