Since the copper under the paint has not had the same exposure to oxygen, it's patina is likely to be different than the existing exposed copper. We recommend that you strip the old paint using either a heat gun or a chemical stripper (test a small area first). Then, thoroughly wash the copper gutters with a diluted solution of white vinegar and water to remove any contaminants.

Then, you can retreat the entire copper surface with a range of patination finishes available. Some excellent sources of information include:

In addition, two excellent books are available on the subject:

	The Colouring, Bronzing and Patination of Metals by Richard Hughes
	Contemporary Patination by Ron Young

Depending on the existing patina, copper can have nearly a dark brownish-black color, or a rich greenish-blue patina.
