With regard to hammerite and with all paints you have to stir them well initially and not shake the tin. This will intriduce small air bubbles which in turn won't give the best protection on the steel surface. All mild steel will rust in the presence of oxygen. Oxygen will be able to permeatate through the tiny macroscopic holes to the steel surface and not give the best protection. Because any surface rust is slightly alkaline (i.e. Iron) then the surface should really be treated with a mild acid to neutralise any molecules left after rubbing the rust off first. Merely painting over the top of rust will not stop the rust.

Mind you, any paint is better than none.

Nick.
