Birchwood CaseyPresto Mag Liquid Gun Blue for Steel Complete Reblue Application, Gun Maintenance and Preservation, 3 Ounce (90ml)

I redo WWI, WWII, & Vietnam era Rifles and sometimes the parts need to be reblued, and this has worked very well and stays on the parts/firearms nicely

It works very well. When using this buy more applicators and poor the liquid you are going to use in a cup so you don't contaminate the rest of the bottle.

I tried my hand at bluing an old knife blade. I cleaned off the rust polished the blade and at last blued the blade. Blade came out great! How long the bluing will last, time will tell. The process was easy enough.

I like how this works. It was a clean finish, and you will not be disappointed with it.

I made a knife from a railroad spike. I used this product to blue the knife. It required several coats. Instructions didn’t say but I think it delutes the product if you use it out of the jar so I put some in a bottle cap and threw the remaining solution in the cap out when I finished.

Redid some items and they turned out great ! And simple to use too! Product is terrific for your touch ups on firearms!

Worked fantastic on my fitted bayonet lug, after initial cleaning and prep with fine steel wool applied with a q-tip after pouring in a separate container to avoid contamination it started with a nice blue tone and after repeated go throughs it ended up matching the same blueing on my WASR-10 AKM barrel at that point I rinsed and toweled it off and then blow dried it to make sure it was absolutely dry before I applied oil now it's absolutely showing no signs of having been worked on and I feel like a more qualified gunsmith after having used it. 11/10

I followed the directions but it still didn't get very black like I was led to believe.
