THIS CONTAINER Can only be repaired with Corten Steel.!!!
Corten steel is designed to rust on the surface. Once the surface rusts no further corrosion takes place. the use of regular old carbon steel would eventually corrode all the way through and degrade the container. Cor-Ten Steel [US Steel] was very popular in the 1960's and 70's, as it was used where surfaces were exposed to weathering/oxidation
