Achieving the perfect finish on a metal sculpture—whether matte or glossy—requires careful technique and the right materials. For a matte finish, start by sanding the metal surface with coarse-grit sandpaper (80-120 grit) to remove imperfections. Gradually switch to finer grits (up to 400-600) for a smooth, non-reflective texture. Alternatively, chemical treatments like acid etching or bead blasting can create a uniform matte appearance.

For a glossy finish, begin by polishing the metal with progressively finer abrasives, ending with a buffing wheel and polishing compound. Electroplating or applying a clear lacquer or epoxy resin can enhance shine and durability. Glossy finishes often require protective coatings to prevent tarnishing.

Both finishes benefit from proper surface preparation—cleaning and degreasing the metal beforehand ensures better adhesion and longevity. Experiment with different methods to achieve the desired aesthetic for your sculpture.
