Which is the better choice, and why? Brass or nickel silver?
The only advantage of one over the other is the colour of the metal - 'yellow' or 'white'. As I paint my nameplates by coating the whole surface then sanding back once the paint is dry to reveal the metal lettering and raised edge of the plate (followed by a coat of varnish to prevent tarnishing) I would generally use a brass plate if I want brass lettering, and nickel silver if I want silver lettering.
Thanks, Julien, then brass it shall be.
