While a lot of cameras have chrome or brass, there are also a lot of cameras that have their metal parts covered black.

I would imagine that these black finishes are some sort of sprayed on and baked on finish designed to be durable and to stick on the metal.

I have run across some cameras that I would like to buy because they work perfectly and are available at a very reasonable price. But they look atrocious, mostly because of missing black on the matal parts.

Short of having these metal parts professionally recoated, what are the other options? By that I mean what specific products have you used to coat the metal parts on your camera so that everything looks as factory new as possible. And if you have used any specific products that worked real well for you, did you also use any special procedures to do it.
