To get an antiqued look, you can replate die cast with our Flash Copper Kit, then use one of our antiquing solutions on the copper plate. You can also brass or bronze plate it, after copper plating.

Thank you.
It is not magnetic but I still haven't checked for acid.
I have a further question about the antiquing solution. Will that cause all of the brass plating to darken evenly? Because it looks like the low spots where the lettering is embossed in the plate are supposed to be much blacker than the rest.
