It took me a while to get around to refurbishing the rocker, because I have had far more important projects to finish.
The rocker was missing a few screws, so the frame wasn't even really intact. There was a great deal of rust and flaking paint. Lastly the wood had lost its protective coating. The wood had turned gray and developed water stains.
I took it completely apart, and used a wire wheel to remove the rust and flaking paint. All the wood I removed, sanded down to clean surface, and coated with a paraffin-based sealer.
