To paint and repaint a metal object, the railing of a balcony or fence will have to be; first of all remove the raised paint by passing with an iron brush.

There are also some iron brushes to be applied to the drill which facilitate the operation.

If necessary, use some sandpaper to improve the surface if it is too rough.

Once the raised paint has been removed, the anti-rusting agent will be applied, insisting well on the metal parts that have remained uncovered and rusty.
