Hey Dez, This method certainly seems easier to me then the reverse electrolysis method I've read before. I'm definitely going to try it one day on a canon P...maybe I'll practice first on a Fed.

Yes, you can paint it black, but it needs to be done properly if you intend to use the camera. You can't get paint to stick to chrome, no matter what any manufacturers may say.
Take off the top and bottom plates and use a hydrochloric acid bath to remove the chrome; this only takes a few minutes. This acid is very dangerous, and may be difficult to get in Europe. In North America, it can be found in some hardware stores for etching and cleaning concrete.
Following that, the underlying nickel plate can be removed using a sulphuric acid bath. Car battery acid is strong enough for this step. This will leave you with a slightly matte finish on the brass parts. Although I have seen recommendations to polish the parts at this time, I disagree: the etched surface provides a "tooth" for adhesion of the paint. Make sure everything is very clean before proceeding.
Next, put on a thin coat of automotive black primer paint. I use something calling itself a "self-etching" primer, and it sticks well. If you like a relatively matte finish, such as the black chrome finish on Leicas, you can use this same paint as a top coat. Otherwise, after it has dried thoroughly, give it a few coats of high quality gloss enamel. Fill in the engravings with white paint stick, or a wipe of flat white water-based paint after the black is thoroughly dry, and you're good to go.
You really do have to strip down to the brass for the paint to adhere properly. If you are not experienced and comfortable with the handling of acid, just decide that chrome is beautiful. These chemicals are dangerous.
Cheers,
Dez
