A man with a lot of bronze sculptures in his house wants me to help him. He has had them for years up in Mexico City where the air is dry. He moved to a seaside house down here and his bronze has begun to develop little white crusty spots in places.
I am not a patina expert. I do my own work but I don't want to do something stupid to his. There are no patina experts down here. There are also none of the chemicals that Ron Young recommends for bronze disease.
I am considering using a small knife blade and scraping the white powder off and then coating the pieces with nitrocellulose lacquer. They definitely need to be coated exposed to the ocean air as they now are.
