If parkerized, take a look at some of the paints available.

I rewelded a sight onto a CETME. Prior to assembly, I touched it up with a little, and it looks like factory.

Brownells has this youtube video on bluing.

And, I am pretty sure that MidwayUSA also has some videos on bluing, but they are usually only about 90 seconds long.

I don't think it would look that good on an AR.

Ok. So my AR is "hard coat anodized" so is this the same type of idea as bluing on steel. I know that aluminum doesn't oxide normally so just how well does that Casey aluminum bluing really work at fixing scratches?

Wrecked the back of a worn-bluing High-Power with such stuff. Thankfully the Pachmayr Grips cover it...

I have used a product called black magic on a blued surface and it worked well. Not sure about other finishes.

Your AR 15 upper receiver is aluminum. The barrel is steel. Each will require a different method of coloring. Cold bluing will not work on the aluminum. There are touch-up solutions for aluminum. These will only color the scratches. Remember to oil the steel parts after touch up.

Well I just used the Casey's Bluing kit on some scratches on my AR barrel and front sight post. The results were pretty good.

I didn't follow all of the directions because the first part calls for removing all of the old bluing which I was not going to do for just a few scratches. Here is what I did.

1) First is degrease it with spray.
2) Then rinse the area with hot water and Dawn soap.
3) Dry thoroughly and take some 0000 steel wool and rub the area down with soft-medium pressure.
4) Rinse with hot water again until the metal is very warm. Dry.
5) Apply the bluing and wait about a minute.
6) Rinse with water and dry.
7) Lightly sand the area with 0000 steel wool again to blend the area.
Repeat steps 4-7 until you acquire the desired color. It took me about 5 times.
8) Wipe down the area with the Birchwood wipes that are provided.
