Rust has been the cancer of iron and steel since
the dawn of the Iron Age. For the farmer, rust is responsible for a great
financial loss over time. Wet environments, corrosive chemicals and fertilizers,
and non-neutral soils all conspire to destroy buildings and equipment.
Zinc galvanize and ordinary paint can delay rust, but after a short time,
they wear or flake away and the problem returns. Ordinary paints require
rust to be sanded, sand blasted, acid etched, or otherwise mechanically
removed before they can be applied. This process is very labor intensive
and prone to error.
