If the surface is lacquered, it will be impossible to darken the brass, unless the solution is particularly strong and the lacquer is thin enough to be eroded by the acid.
That would take prolonged exposure and the oxidizng solution would probably evaporate before it could do serious damage.

Without knowing what settings you are using, I would suggest a slow speed with a high power. Brass absorbs heat like a sponge so you have to make sure the power is high to make a mark. At least, that was the explanation I got when I tried brass. I'm certainly no scientist LOL.

Yep, it had a finish on it, but I got lucky and got the Cermark to lay on pretty good. I took Stunt Engravers suggestion and ran the laser across it first, then applied the Cermark and ran it again. They came out real nice. Thanks much!
