Ok. So from there boil after the first initial coat, card and do it again.

No Appy a second coat and then boil.

Then one coat one boil there after

No one pointed out it need to be distilled water or rain water!

Nope.

tap water works just fine.

Distilled or rain water for actual hot salts blue. the reason is copper sulfate in tap water will kill hot salts mix and cause spotting.

in slow rust blue you are using humidity to induce rust on a treated part. the acid is doing the work

the boil is done after the acid has done it's job. i don't see the need for distilled water and had no issues. Brownell's makes no mention of distilled water for slow rust blue

Correct me if I'm wrong here, but I was under the impression that the heat from boiling was what caused the color change, not a chemical reaction to the water. I have used Brownells rust blue a couple dozen times and the first coat is always fun. Some where around the tenth coat you start thinking why didn't I just use cerakote. In the end it is worth it tho, just takes forever and is messy.

yep heat causes the ferrous oxide to change to magnetite... that all there is to it.

just hope to clarify....if you're doing 8 coats then it takes a week because you need it to rust over night?

I do a minimum of 12 applications, and yes it takes an over night rust at least in my area with the humidity i have. The issue i was having was it rusted up just fine but didn't bite in the steel. I could wire it off like it was nothing. But if I let it sit over night and worked on it the next day. it was fine. then it would build the gray that deepens to black over the next applications.
