Birchwood Casey's touch up pen does pretty good job of it. Drys up a bit glossy but it'll dull up after few rubs.

DuraCoat comes in 150 colors and 4 sheen's. If the finish is DuraCoat My suggestion would be to properly prep the area and use DuraCoat. The finish becomes the rust protection for the metal. Depending on the surface to be touched up a compromise in the finish could lead to rust.

It also depends on what you're touching up. Aluminum and its alloys don't work with standard cold blue, so an AR upper or lower needs aluminum blacking for that.

If it's on steel, cold blues (like hot blues) take differently on different alloys, and it can be a bit unpredictable how they come out in terms of color, deepness, sturdiness, etc. It really takes a bit of testing, which can be tough if you don't have other parts made of the same alloy.

If it's important, I'd agree that a Duracoat touch-up would be the way to go. If it's just to take the shine off and make it black so it doesn't stand out, almost anything will work if the spot's not too big.

Nothing. Scratches are character.

touching up aluminum

If you just want to make the recvr. a dark blue/black color you can use Aluma Black. Its like a cold blue touch up except for aluminum

i ask cause there a re a few little spots on my ar and the walther g22 i just bought has an a2 flash suppressor epoxied on the end of it and if i take it off i have to get the epoxy off and well im sure the finish at the end of the barrel will be shot!(no pun intended)

Try Tamiya model paint (flat black). It is an acrylic base goes on like a
"coating" so its hard to chip off, and water clean up. The semi-gloss color is
good for scopes.

i need to make sure its fairly solvent resistant. i touched up my rifle with a sharpie and clp wiped it right off few days later.
