has anybody tried something simmilar? I belive this could be used for enclosure etching, using toner transfer?

Yep, I've tried it works well. I used an icecream tub of saltwater, an old computer power supply for 12V with an automobile headlight bulb to limit the current to 1 or 2 amperes.

Though getting the toner mask perfect is the crucial part, maybe even more than when doing it with acid, every tiny little hole in the mask becomes accented greatly, that and the undercutting issue.

I've been getting parts together to try it but still a few days away from a test.  I'm trying to locate a source for photosensitive stencils to use instead of toner.

I've tried and failed with this method on PCBs, but it would probably work better for enclosure etching. You'll want to do this outside, because you will likely get chlorine and hydrogen gas. I started my test inside but stopped once the room started to smell like a pool.

Well you can trick people into thinking there's a pool somewhere near your house

Chlorine gas is seriously dangerous, way to go with your instincts. It can kill you, if you're lucky. If you're not lucky, you can spend months in the hospital as they try to put your respiratory tract back together.
