Good question! It is to get the pits. I rust it long enough that the pitting goes below the surface of the barrel just enough that when I sand everything back I end up with some color left on the barrel, and some pits where I get all the way down to steel.
I sand off most of the rust first, then I put on the naval jelly and as you've probably seen, it turns the remaining rust black and the steel grey. So when I finish sanding the pits are black. Then I use the cold blue to try to get a color I like.
I have a .50 cal that I just finished up and I'll be posting some pics soon. I'll show some closeups of the barrel.
