B.C. super black on regular steel?

[old fart]

i just reblued an old revolver and have been trying to figure out a finish that would hold up at least fairly well. everyone i spoke to has told me the bluing will be gone in a short time. a friend of mine just used some of the birchwood casey super black pen to do his pistol. i beleive this is for alloy but he used it on steel, it has held up good. i thought someone here would know for sure, will this work on regular steel? he said just a thin coat and give it a day to dry, i am woried that rust might get started under the coating. thanks for any help.

The B-C super-black for aluminum is a paint pen.
It is intended only for touching up scratches on anodized aluminum firearms parts.

The best cold blue I know of is Brownell's Oxpho-Blue.

But it is still cold blue, with all the attending cold-blue durability problems.
Just not quite as many.
