No aluminum, its a cast pot metal

Satin black and satin nickel for paints

To actually redo a pot metal grille with chrome, is a time consuming process, to do it right. First stop is chrome shop, chrome before paint, then any areas that need paint, chrome needs to be scuffed with fine grain paper, paint doesn't stick to chrome very well, any rock chips, nicks and pits are filed out with flat files then filled with bondo, sand primer, paint, install. I've spent over 150 hours on just one side of a grille filing filling and sanding.

If your grille is rechromed you shouldn't have any nicks/pits... but rechroming a Beaumont grille will not be a cheap project, especially at a show quality chrome shop. If you do explain what you plan on painting over after, it could bring the price down, as they won't prep those areas the same.

The horizontal bars, painted areas get chips the worse, you're right the chrome areas are well protected

Ya could always grab a second complete grille, work on it in spare time, then either sell or keep the spare
