Bluing touch up
Well I got some scratches on a new AR that I got and also have some on the barrel of my hunting rifle.


So does anyone have any experience in DIY bluing touch up jobs? Any recommended products? Has anyone used the below product?

Or this product seems to have higher ratings.

IMO the only cover-ups that seem to work perfectly come out of The White House.

Thanks Hock for the quick humor but I really do have a problem here that I want to fix quickly.

I've used the perma blue cold blue many times & am always amazed at how well it can work. I had a spot on my CZ70 that the blue was completely worn off, the spot was about 3/8" in diameter. after a couple coats with the perma blue & some polishing with a paper towel you can't tell the spot was ever there.

it takes a bit of practice to get a good finish but it does work

Will you explain the whole process to me? I don't want to F-up

For scratches and touch ups that Birchwood Casey cold blue works great.

it's pretty simple, clean & degrease the area, remove any rust, dab some cold blue on the scratch with a q tip or cloth, let soak for 30 seconds to a minute, wipe off & blend with a paper towel, cloth, or steel wool. repeat as neccessary

don't expect the scratches to disappear, especially if they're deep. you'll just color them to match and they won't
be as noticable. they only way to completely elimnate the scratch is to polish it out and then reblue. a much bigger
job than a touch up.

Don't get me wrong, most of the time the touch up looks great if you aren't expecting the wrong thing.

chose the right product. If the area is aluminum, the perma blue wont do anything. if the area is steel, the
aluma black is useless.

you can order some good products at Brownells ( as well and they have some on line instructions.

which ever product you use, clean and degrease with 90% isopropyl Alcohol 1st. (anything less than 90% leaves residue)
you can get it at any drug store, or walmart, etc.

apply with a clean cotton cloth (i use make up pads). don't use from the bottle, put some of the bluing chemical in a dish or something and work from there to keep from runing the remaining chemical.
If it's steel you can apply the chemical with 0000 steel wool. it's fine enough not to add scraches if you dont press hard.

it's not hard to do. good luck.
