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.
