Many of you may remember, I bought a ‘clamp-on’ brake? Anyway, I installed it, am wishy-washy about the look of it, just not sure I like it. So I took it off, when I did, I found that it left a scuff/scratch where the clamp is tightened and squeezed together. I have some Perma Blue, so I thought I could touch it up. I’ve watched a few YouTubes on it, but haven’t found one on repairing just one scuff. They mostly go over bluing the whole barrel, or something entirely different that I don’t need.
Can anyone tell me the steps of this, do I just need steel wool and alcohol for cleaner? Do I need to mask it off, and only get it on the scratched area? One more thing, my Perma-Blue is about 2 years old, although it’s unopened, is it still good?
Here’s a picture of the damage, not a great picture, but maybe it’ll help...

First, take some 4-"0" (0000) steel wool wet with Hoppe's or some other solventish fluid. Give it a good scrubbing. See how it turns out.
Lemme know how it turns out.

I moved ahead and tried the Perma Blue, since I had it on hand. It definitely darkened it noticeably, but after 8 coats, it’s still not to my standards. I may need to try Super Blue to get it where I want to. Is the Super Blue noticeably better than Perma Blue, worth my time/money? Or would I just be wasting my time?

At first I tried heating the area with my heat gun (was still cool enough to touch). I saw the heating method on a couple other forums/videos, although the bottle directions said nothing about heat, others said this is “the only way to go”. It almost looked as though it was baking it off, so I let it cool to room temperature and tried again. With no heat applied, it seemed to work much better.

Any thoughts? Ideas? Concerns?

The BEST cold blue I've used and seen is Brownells Oxpho-Blue, the liquid. They also have a cream version but I cant vouch for that as I have never used it. If you were closer, I'd say bring it on over and we could touch it up easily. (I live in Yukon). Amazon has it as well as direct from Brownells and I've seen it at Cabela's too.

Get the super blue and some perma blue paste from birchwood.
alternate coats for about 4 of each then just the paste until you get the desired results . Don't sweat removing the oils, just clean it and heat the part to around 150 between each coat. Apply by hand and rub the paste in thoroughly. Super apply with cotton balls and rub it in thoroughly as well, I used gloves with the super but not the paste. ( only developed a slight twitch LOL) Let each coat sit for 5 minutes then rinse in warm water dry and repeat.
