Protective Clearcoat:

Our shutter caps are made of copper, the same material used for copper roofing and gutters. If left unfinished, in most climates they will weather to an attractive patina that is generally a rich dark brown to black, with a hint of green. If you prefer to maintain the bright copper color, we also offer an exterior grade acrylic clearcoat. Alternatively, you can periodically polish the caps to restore the bright copper finish [we use Tarn-X brand metal polish].
