gun blue won't work on  AL....the blueing process is actually controlled rust...you might try permanent marker.....

There is an aluminum blacking solution that is sold at firearms places (Formula 44? or Birchwood-Casey)

Most "cold blue" solutions are a nitrating solution, and don't "rust" blue, at all.(Oxpho-blue, etc.) they will NOT work on aluminum. Some (most) bluing solutions are caustic, and dissolve aluminum, or etch it badly.

Firearms shops even have the marker pen type blackeners for aluminum.

Though I would chime in with My two cents worth as a gunsmith with 20 years experience bluing, browning, parkarizing, rust bluing and refinshing all types of gun metal. The best productI have used for refinishing Aluminum/alloy shotgun and 22. auto recievers is Brownells Aluma Hyde original and Aluma Hyde 11. This is a specific primer and/or paint that will closley resemble anodizing on aluminum, have several differnt colors and a tech line that will help. The only down side to Aluma Hyde II is that it is slow drying, as it is an Epoxy paint, may take up to 10 days to dry completley, but is tough as nails when it does. I have also used it as stock paint on varmint rifles that see a lot of rough use and has held up well, even painted a recurve camo for a friend with it! Hope this helps.

I have used a Birchwood Casey called Aluminium Black to touch up aluminium parts on firearms with some success. Have found that the metal needs to be free of oxidization and really clean.
Looks best if oiled regularly.
