Etching brass?

[nachoman]

has anyone here ever considered brass etching as a tool for model building? While searching for information on PCboard etching I ran across this:

I have etched copper clad PC boards before with great success. But I have been considering ways in which the technique could be used in model railroading. This could be useful for making brass detail parts such as grilles or even scratchbuilding locomotives out of brass. I am wondering if this technique could also be used to make a stamp or a stencil for applying logos on decal paper, or even spraying logos directly on rolling stock.
