We sprayed a light mist of very mild acid last week to start the rust patina process on the giant drum which will soon be bound for the Arctic Circle. I was amazed at how quickly the rust formed on the special Corten weathering steel as we had hoped. We were pleased to see that it wasn’t nearly as mottled and uneven as is usually the case on normal steel. It is looking great! Watching steel rust is even more exciting than watching paint dry!
