PLEASE... Read the whole thread...
there is MUCH good information there...
The process ... in a nutshell....
1. Bead blast the part you want to blue...where you want it blued.
2. Degrease EVERYTHING throughly
3. Wipe on a VERY THIN COAT OF RUST BLUE...its not even a "coat"... just barely get the parts that you want blued...damp...not wet!!! ... the more you put on...the more trouble you'll have getting the blue you want. JUST WIPE IT WHERE YOU WANT "BLUE"...
4. Boil the parts...in WATER. Distilled if you can get it....at least filtered tap water.
5. Take the parts out of the water, Hang them up and let them rust .... the red rust color will be the blue.
6. "Card" the parts with a stailness steel wire brush...."Carding" means brushing off the rust...this can be messy....wear old clothing...and gloves....do it in an area that you can clean easily...
7, 8, 9, 10. Repeat until you get the blue you want. 4 repeats should do it.
I would refer you to the first set of pictures of the AK parts...look into the chamber...what do you see...?
The chamber and bore NEVER get sand blasted...They NEVER get wiped with the chemicals...
NO CHEMICALS EVER GET INTO THE BORE or CHAMBER!!!
There are NO chemicals in the water!!!!!!
If you have concerns about BOILING WATER getting into the bore... pull a cleaning patch through the bore to get out the water after you take it out of the tank and before you hang the part to "rust" ...
This process is
NOT like caustic blueing...where you boil the part in the solution.
There is NO REAL NEED to plug the barrel.
Throughly read the thread...all the information you want/need is in there.
