You can accelerate the verdigris patina process by spraying copper with a mixture of copper carbonate, ammonia and water http://experts.about.com/q/Metals-24...-verdegris.htm

Once it reaches the desired color of green, a clear coat of paint could be applied to protect the delicate plating. I'm not sure how the verdigris would react to the solvent in the paint though, so I think you would want a few very light coats at first.

There is also a copper paint, and oxidizing compound crafty folks use to give a verdigris effect to non-metalic objects. I'm not sure if the paint is suitable for a frame, but you might want to check it out. http://www.timeout4me.com.au/140.htm

cheaper way to speed up the patina process is to just piss on it... really... it works... long story, but it works. The question is do you really want to piss on your bike?
