I'm in the process of buying a 19-4 official S&W commemorative revolver with gold-filled engraving on the side plate and right side of the barrel. Does anyone know if it is paint, gold leaf, or electroplating? How careful do I have to be with CLP products around it? Can I wipe the area down with Break-Free or Ballistol without harming the engraving? If I wanted to remove it entirely, how would I do it? Thanks.
