Is there a safe way to remove the black finish from Shoei Model Guns?

Does anyone know if there’s a safe way to remove the black finish from Shoei Model Guns?

Not sure about the shoei but all other metal models solvol and a rag or a dremmel, comes off easy on most models but as i say i dont know how good the bluie finish is on a shoei

Thank you for your response. Solvol is a very good gritty polish, one that might add a shine to the metal. My desire is to have a low luster, Matt type result. I suspect a chemical dip of some sort. My fear of sandblasting or Aluminum Oxide blasting might remove the Zinc or Zamac as well?
