I made a trigger guard from aluminum and need it to be black. What is the best and easiest way? I think that the best way might not be the easiest way so I`m asking for help.
Thanks in advance

The best is anodizing.

The easiest is spray paint.

The second easiest is Birchwood Casey's Aluminum Black. It's like Cold Blue, but for aluminum instead of steel.

I'm with JLA. Or use Brownells alumahyde.
