We have an octogonal birdhouse which has a copper dome , about 18 inches across, on top. All the wood rotted so I rebuilt it & now need to put the copper dome back on top. It was held in place previously by some type of glue or caulking. What glue/caulking would you suggest that I use to connect the copper dome to the wood beneath it? I might add that the bottom of the dome which sits on the wood is only about 1/8 inch wide.
Thanks
Dennis
