I have down browning, and thought all bluing was hot blue.
Now I’m reading about cold rust bluing - which sounds like it would take forever but might be worth a run just to see what it’s like.
Disclaimer, I’m setting up for Cerakote, I have a TP tools blasting cabinet, and building a Cerakote oven, time wise I’ll do cerakote, but it’s hard to beat how really nice blueing look IMHO.
