What can I use to coat metal to prevent rust?

Galvanize: Galvanizing coats iron or steel in zinc to protect from rust. Zinc corrodes at a much slower rate than iron or steel, so it’s highly effective for slowing rust. Blueing: This process creates a layer of magnetite over the metal to prevent rust.

What oil prevents rust?

You can prevent rust easily by coating the metal object with an oily shield using a cloth that has been treated or trunk with linseed oil. Boiled linseed oil dries faster than cold-pressed linseed oil, and forms a much harder surface.
