For a long time I have wanted to rust blue one of my AK's. I finally did it, or started anyway. I started with most of the smaller parts, and it is a very simple process. The rifle is the fist one I built with the help of bam bam way back in 08. I started by blasting all of the parts then degreasing with acetone. I used Laural mountain brown and degreaser. It is easier to work with, you don't have to be as careful with the fingerprints.
Once the solution is applied parts are left to rust.
Once there is a good coat of rust parts are placed in boiling water for 5 to 10 minutes. Distilled water must be used.
When they are removed from the water there will be a coat of black soot on the parts. This has to be carded off. I was using a stiff wire brush at first and it was too rough and removing some of the blue so I switched to 0000 steel wool and one of those green military brushes and the parts started to look better.
It usually takes between 4 and 6 cycles to get the color your looking for, once done coat with boiled linseed oil and let sit for a couple of hours and your done.
